Great...This is a difficult topic for many.

[@amanikkirichards8878]

You are a god!! Jesus christ😭 I didn't understand a shiittt now I finished all my homework

[@comesazm]

Thank you so much for your help😅

Y /2 = 6 when you have a question students try to find it difficult when you have a formula as fraction you have the next side as the same fraction so it will be is Y /2 = 6/1 and the formula is a×d and b×c which is ad = bc and that is called cross multiplying so is Y/2 = 6/1 cross multiplying so therefore y =12

[@mightymemes412]

Sir for question, 7/2y= 2x , can the answer also be y = 7-4/x

[@lewisgeorge-cole987]

for making n the subject in wouldn't n= 5m/t^2 /12 because the opposite of multiplication is division

[@scrumdiddlyumptious3001]

Thank you for this

[@kellyannmathieson243]

can you do some multiple choice questions before the 18 may

[@CSECMathematics]

+Kellyann Mathieson Unfortunately I cannot post any actual multiple questions on my channel. I will be doing model type questions similar to what may come. But I don't think I will be able to record before next Wednesday.

[@reremason3234]

CSEC Mathematics videos are great

[@reremason3234]

CSEC Mathematics Any lessons on the speed time graphs??

[@sharonamartin4650]

hi, im a bit confused with the question f=9/5+32 question why didnt we just put the 32 over 1 n make it a fraction, then cross multiply like the other fraction ones shown? why was the f also multiplied by 5?

[@CSECMathematics]

I multiplied everything by 5 to avoid the fractions. But you can do it the way you've suggested as follows: 9C/5 = F - 32 9C = 5 x (F - 32) 9C = 5F - 160 C = (5F - 160)/9

CSEC Mathematics thank good teaching hw can I get this web site

[@Sowmya_666]

Hi sir excellent method.of teaching.....

[@ayannalewis8470]

Afternoon sir

[@allyhamil6156]

Sir for the last question I had the 5m at the top and t squared and 12 at the bottom is that still correct

[@CSECMathematics]

It you write the t squared first it is still correct. By convention we will write it as 5m/12t squared

[@allyhamil6156]

THANKS

[@sharmainmoriah2007]

Thank you so much so muchh

[@pwettyabii9128]

LISTEN TO ME NUH!!!!!!!!!!!!!!!

[@JR-Johnny]

Sir can u please help with.biology and hsb paper 1

[@natashaivey7785]

What if i want to make t the subject

[@DinishaJoseph]

Good morning sir ans students

[@ayannalewis8470]

Seven divided by 2 we have make y the subject of the formula so the first thing we do we write 2×\1so 7/2y=2×\1again we going to cross multiply so 2y×2×is going to give us 4× so 4×ywhich is equal to 7 ×\1which will give us 7 if i want to make y the subject of the formula I have to divide both by 2y so we end up with 4×=7 so is 4×\4×=7/4so then x will cancelled and we will end up with y=7/4like I said when this become second nature to you you will write as 7/2y=is 2yand this will be written as 7/2y is =2×\1cross multiply so we end with 4×y=7we have to make 4×and this become y =7/4× right

[@ayannalewis8470]

2×=6-y = 2×+y = 6-y+ y = 2× +y=6

[@ayannalewis8470]

5y +2-2=×-2/5 y = ×-2/5 5y +2

[@allyhamil6156]

Sir Question how you got the 4 squared. Great teaching thanks so much

[@CSECMathematics]

Let me know the exact time in the video

[@ayannalewis8470]

5 y =10 = 5y/5 =10/5=2

[@anaysar_beaded]

Exam tmr😭

[@pwettyabii9128]

SIRRRRRRR UH OLD INNA AGE OR WAT? CAH FIRST UH SEH 6 Y NOW UH GONE A DAMNING OLE 4 Y

[@jaydonquamie8120]

19:18

[@ayannalewis8470]

Y+2=×=y+2-2=×-2=y=×-2

[@DinishaJoseph]

y+2-2=×-2 y=×-2=×-2

[@DinishaJoseph]

y+5-5=×-5=y=×5=×-5

[@keziathomas4459]

Great video but I had some problems looking at it😫😫i couldn't concentrate my attention span is so short oh lord .

[@ayannalewis8470]

Y +2=x so subtract 2 from both sides of equation y+2 -2 = x -2 = y x

[@ayannalewis8470]

Make y the subject of the formula

[@ayannalewis8470]

Y +2 = ×

[@ayannalewis8470]

Y-5=×

[@leo-elicob8923]

dont understand Much

[@Lilyflower-4]

I don't blame you how will u understand ? Almost everyone that commented understood it .
