Question 913884: If A=3x+100 and B=4x+20, for what value of x does A exceed B by 652.

You can put this solution on YOUR website!
A exceeds B means that the difference A-B is positive. This difference is set equal to 652. Plug in the values of A and B. Then solve for x.

A-B = 652
3x+100-(4x+20) = 652
3x+100-4x-20 = 652
-x+80 = 652
-x = 652-80
-x = 572
x = -572

The answer is x = -572
