9x-\left(5x-7\right)=15
Multiply both sides of the equation by 3.
9x-5x-\left(-7\right)=15
To find the opposite of 5x-7, find the opposite of each term.
9x-5x+7=15
The opposite of -7 is 7.
4x+7=15
Combine 9x and -5x to get 4x.
4x=15-7
Subtract 7 from both sides.
4x=8
Subtract 7 from 15 to get 8.
x=\frac{8}{4}
Divide both sides by 4.
x=2
Divide 8 by 4 to get 2.
