41+4a=8a-7-a
Add -8 and 49 to get 41.
41+4a=7a-7
Combine 8a and -a to get 7a.
41+4a-7a=-7
Subtract 7a from both sides.
41-3a=-7
Combine 4a and -7a to get -3a.
-3a=-7-41
Subtract 41 from both sides.
-3a=-48
Subtract 41 from -7 to get -48.
a=\frac{-48}{-3}
Divide both sides by -3.
a=16
Divide -48 by -3 to get 16.
