-3a+8-15a=24
Subtract 15a from both sides.
-18a+8=24
Combine -3a and -15a to get -18a.
-18a=24-8
Subtract 8 from both sides.
-18a=16
Subtract 8 from 24 to get 16.
a=\frac{16}{-18}
Divide both sides by -18.
a=-\frac{8}{9}
Reduce the fraction \frac{16}{-18} to lowest terms by extracting and canceling out 2.
