-17=-18+6a+4
Use the distributive property to multiply 6-2a by -3.
-17=-14+6a
Add -18 and 4 to get -14.
-14+6a=-17
Swap sides so that all variable terms are on the left hand side.
6a=-17+14
Add 14 to both sides.
6a=-3
Add -17 and 14 to get -3.
a=\frac{-3}{6}
Divide both sides by 6.
a=-\frac{1}{2}
Reduce the fraction \frac{-3}{6} to lowest terms by extracting and canceling out 3.
