9-3a=8a+3-a
Add 2 and 7 to get 9.
9-3a=7a+3
Combine 8a and -a to get 7a.
9-3a-7a=3
Subtract 7a from both sides.
9-10a=3
Combine -3a and -7a to get -10a.
-10a=3-9
Subtract 9 from both sides.
-10a=-6
Subtract 9 from 3 to get -6.
a=\frac{-6}{-10}
Divide both sides by -10.
a=\frac{3}{5}
Reduce the fraction \frac{-6}{-10} to lowest terms by extracting and canceling out -2.
