-84+15-5b=14-8b+6
Subtract 96 from 12 to get -84.
-69-5b=14-8b+6
Add -84 and 15 to get -69.
-69-5b=20-8b
Add 14 and 6 to get 20.
-69-5b+8b=20
Add 8b to both sides.
-69+3b=20
Combine -5b and 8b to get 3b.
3b=20+69
Add 69 to both sides.
3b=89
Add 20 and 69 to get 89.
b=\frac{89}{3}
Divide both sides by 3.
