12x+3=2x-15-x+2 then add two x to both side and solve your answer
Your answer is: x= -22/5

Here are the steps:

Expand:
12x+9=7x-13

Subtract 9 from both sides:
12x+9-9=7x-13-9

Subtract 7x from both sides:
12x-7x=7x-22-7x

Simplify:
5x=-22

Divide both sides by 5:
5x/5=-22/5

Simplify:
x=-22/5


Thus, x=-22/5.
