7x+5x+15=9
Use the distributive property to multiply 5 by x+3.
12x+15=9
Combine 7x and 5x to get 12x.
12x=9-15
Subtract 15 from both sides.
12x=-6
Subtract 15 from 9 to get -6.
x=\frac{-6}{12}
Divide both sides by 12.
x=-\frac{1}{2}
Reduce the fraction \frac{-6}{12} to lowest terms by extracting and canceling out 6.
