The answer looks like it would be 10. Just distribute, add your x's together that you have on the left side, and then add 1 to both sides.

3 (x-1) - 2x=9

Distribute the three

3x-3-2x=9

Simplify

x-3=9

Add 3 to both sides

x=12

Check:

3 (12-1) - 2 (12) = 9

3 (11) - 24=9

33-24=9

9=9

There fore x=12
