If you add 2 numbers the result is 188 if you subtract the numbers you get 34. What’s the numbers?

[@JasonBell101]

I solved this simply in my head without reaching for algebra. There were three steps. 1. Start at the half way point, 188/2 is 94 2. Halve the difference, 34/2 which is 17 3. Add and subtract to get the two numbers. 94 + 17 = 111 and 94 - 17 = 77 Simples ☺️

[@reiniernn9071]

My solving is a little different. Without using paper in a matter of a few seconds. A+b=188 A=b+34 2*b+34=188 2*b = 154 b= 77, a = 111 (b+34)

here is a tough one for you.... what if it was x² + y = 148 and x - y = 8. if you want to answer, answer fully.

[@chrisdissanayake6979]

Let the two numbers be X and Y. X + Y = 188 -(1) X - Y = 34 -(2) Adding the two equations, 2X = 188+34=222 2X = 222 X= 111 Substituting this value of X to the first equation, X + Y = 188 111 + Y = 188 Y= 188-111= 77 Therefore, the two numbers are 111 and 77.

[@chuckmoore1380]

I actually chose a different route. Since we are told the difference between the two numbers is 34, I used this equation: x + (x+34) = 188 which simplifies down to 2x + 34 = 188 2x = 188 - 34 2x = 154 x=77 Plugging that into my original equation: 77 + (77 + 34) = 188 We now get the two numbers: 77 + 111 + 188

I did it in my head in around 12 seconds. half of 188 is 94. Half of 34 is 17. Add 17 to 94 and it equals 111 Subtract 17 from 94 and it equals 77. 111-77=34 LOL It actually took longer to write this than it did to solve it in my head.

[@MayBeMe...]

I never learned Algebra, I just took 188 minus 34 = 154 divide by 2 = 77 then add 34 to "one of the two" 77's making one "111" and leaving the other at "77" and that makes the two numbers "111" and "77"....using Algebra seems messy.

[@bigdog3628]

super simple we have two equations with two variables. Let x equal the first number Let y equal the second number x + y=188 and x - y=34 y = x - 34 We have a value for y so let us plug it into the x + y equation x + [x - 34] = 188 Now we combine x's and isolate with subtraction this gives us 2x = 222 x = 111 Now that we have a solution for x we must find the solution for the y variable by using substitution. y = [111] - 34 y = 77 Now we must prove our solutions. 111 + 77 = 188 and 111 - 77 = 34 This proves that x does in fact equal 111 and y does in fact equal 77
