Question

Which value of x makes the following equation true?

3(x - 3) = -2x + 31

12
8
11
9

Answer 1

You could plug in each of your values to see which one works.

Or, you can do it like this to find x:
3(x-3)=-2x+31
3x-9=-2x+31
3x+2x-9=-2x+2x+31
5x-9=31
5x=40
5x/5=40/5
x=8

Check it:
3(8-3)=-2(8)+31
3(5)=-16+31
15=15

we see that it works!
