You see in a second that 3m/4 has to be -12. So m is a negative number: 3m/4 = - 12 => m => 4/3 x - 12 = - 16. This time no need to find the LCD. :)

[@GaryBricaultLive]

Another problem turned into a vastly more complex solution than necessary. The straight line approach to solving problems is to simplify as you work. 1. Rewrite the equation to place the variable to be solved on the left hand side where it belongs. 29 + (3m/4) = 17 2. Subtract 29 from both sides 29 - 29 + (3m/4) = 17 - 29 (3m/4) = -12 3. Multiply both sides by 4 to eliminate the fraction term. (3m/4) X 4 = -12 X 4 3m = -48 4. Divide both sides 3 by 3 to produce the final result 3m / 3 = -48 / 3 m = -16

[@Ayelmar]

At the title card, m = -16 0) 17 = 29 + 3m / 4 {starting position) 1) -12 = 3m / 4 (subtract the 29 from both sides) 2) -16 = m (divide both sides by 3/4 (or multiply by 4/3, either way works!)

[@twentyrothmans7308]

Thank you, TCM. This one's straightforward, but that's expected, as I read first year Maths at University. The subjects you cover that I love are the ones I've forgotten, playing around with square roots, for example. And to any of you high school/college pupils - practice, practice, practice.

[@MrMousley]

17 = 29 + 3m/4 subtract 29 from both sides 1 - 12 = 3m/4 multiply both sides by 4 2 - 48 = 3m divide both sides by 3 3 - 16 = m THREE STEPS

[@aryusure1943]

I took a short cut after getting rid of 29. I came up with -12 = 3m/4 and used the cross product to isolate m. -12 times 4 = 3m times 1 or -48 = 3m. Dividing both sides by 3 I got the solution: minus 16 = m Thanks for reminding us that 3m/ 4 is the same as 3/4m. I would have followed your path if I had this in mind.

[@MargaretCutt-um8iq]

similar method. knew it needed to be negative... what divided by 4 = 12... then made that negative...lol similar process but that is how my brain works...lol

[@ChoiLanLeung]

17-29=3m/4 -12=3m/4 -12÷3×4=m -16=m

[@totwisted]

If the school system would have teachers like you, students would not struggle in math. Step-by-step made easy

[@Dethneko]

Been a while since I've done one of these, but if I remember correctly, since the division comes first, then you will multiply first to isolate the m, giving us an end result of (4(17))/3 - 29 = m. -> 68/3 - 29 = m -> 68/3 - (3(29)/3 =m ->(68 - 87) / 3 = m -> -87 + 7 + 60 + 1 = -80 + 60 + 1 = -20 + 1 = -19 = m -> m = -19 Edit: Ah, so it's more a reverse PEMDAS (or SA DM E P if you will) when moving things over. I moved over the 4/3 first originally.

[@MarcelDekker-il3vw]

good training. to keep brains running. Thanks for that. I guess its like this reset to 17= 29 + x . X= 29-17 X= -12 come to M? M = 4*--12/3 ( guess -16.. Now watch this vide0 to learn 2 things. Am I right.. an what is the way to solve this.

I can't believe I figured this one out in my head. This 85 year old brain is still in great condition. Eat your heart out Brandon.

[@birdieh1716]

Well done. I did the same. I think it has something to do with the fact that we were taught well in our generation. I’m 61 and I have really enjoyed revisiting algebra after so many years. Let’s keep practising and learning. Never too old to learn.

A great channel, but I don't always agree with you; and that's good, and I am prob. wrong. A bloke's place is in the wrong. That line at the 15 minute mark : 4(17 = 29+ 3m/4) Less confusing to say we have to multiply both sides of the equation by 4 LHS = RHS Multiply both sides by 4 4 x the LHS = 4x the RHS 4(17) = 4x (29+3m/4) We have activated the distributive law as on the RHS we have mixed x / with + - 4x RHS is 29+3m 29+3m 29+3m 29+3m It's four of the things! = 4x29 + 4x3m Including Robert Record's = sign in the brackets confuses the meaning of what an equation is. It has a Left Hand Side and a Right Hand Side with an 'is the same as' sign in the middle. There are two groups, not one, and brackets are about groups; thinking of them as denoting one number sometimes helps. Record made his sign as it is because he could not think of two things more the same as each other than two long straight lines. The Group on the Left is numerically the same as the Group on the Right. To bracket the whole equation blasts the whole concept to pieces. We don't need brackets on the LHS as our group is a simple number represented by a simple numeral. What thinkest thou? Mate: you have sent me to the peppermints. And I deserve a Koala stamp for wrestling with this keyboard.

Thanks for clarification about V=N N=V I was beginning to think it must be a US thing for reasons beyond me.

[@chestermarcol3831]

At the point: -12 = 3m/4 why wouldnt you multiply both sides by 4, and then divide both sides by 3?

[@alcoholfree6381]

Yeah I got it!! Your teaching is great; I’m a 70 year old retired neurosurgeon who hasn’t worked these FUN BRAIN STRETCHES FOR OVER 50 YEARS! I’m substitute teaching at present and sometimes get to teach MATH! I tell the kids that they need to get smarter every day and that requires Reading, Writing, and Arithmetic; the “Three Rs”! I also tell them: “Make it fun, make it a game, shoot for Straight As! Shoot High, Aim for lofty goals, aim for the Stars!” Thanks for your fun teaching.

1} subtract 29 from both sides 2} multiply both sides x 4 3} divide both sides by 3

Is there any other way to quickly solve this equation!

[@bingo1232]

John, love your videos & teaching methods (especially the “bowtie” for fractions)! Question - I got a different answer for this problem. (The algebra checker agrees with your [m = -16] or [17=17] answer.) OK, I got an answer of [m = 13] or [68=68] which I checked 3 times to see if it was right. It was. What do you think? Thanks.

So... I think the reason you talk so much is because you're explaining things that have nothing to do with solving the equation. This is why tutors are needed. Teachers overcomplicating all the time.
