5x+15-2x=x+9
Use the distributive property to multiply 5 by x+3.
3x+15=x+9
Combine 5x and -2x to get 3x.
3x+15-x=9
Subtract x from both sides.
2x+15=9
Combine 3x and -x to get 2x.
2x=9-15
Subtract 15 from both sides.
2x=-6
Subtract 15 from 9 to get -6.
x=\frac{-6}{2}
Divide both sides by 2.
x=-3
Divide -6 by 2 to get -3.
