-3b+8-7b=-7
Subtract 7b from both sides.
-10b+8=-7
Combine -3b and -7b to get -10b.
-10b=-7-8
Subtract 8 from both sides.
-10b=-15
Subtract 8 from -7 to get -15.
b=\frac{-15}{-10}
Divide both sides by -10.
b=\frac{3}{2}
Reduce the fraction \frac{-15}{-10} to lowest terms by extracting and canceling out -5.
