12-5a=2-8-2a
To find the opposite of 8+2a, find the opposite of each term.
12-5a=-6-2a
Subtract 8 from 2 to get -6.
12-5a+2a=-6
Add 2a to both sides.
12-3a=-6
Combine -5a and 2a to get -3a.
-3a=-6-12
Subtract 12 from both sides.
-3a=-18
Subtract 12 from -6 to get -18.
a=\frac{-18}{-3}
Divide both sides by -3.
a=6
Divide -18 by -3 to get 6.
