-9+9x+21x=-2x+1
Subtract 15 from 6 to get -9.
-9+30x=-2x+1
Combine 9x and 21x to get 30x.
-9+30x+2x=1
Add 2x to both sides.
-9+32x=1
Combine 30x and 2x to get 32x.
32x=1+9
Add 9 to both sides.
32x=10
Add 1 and 9 to get 10.
x=\frac{10}{32}
Divide both sides by 32.
x=\frac{5}{16}
Reduce the fraction \frac{10}{32} to lowest terms by extracting and canceling out 2.
