Answer

b=-16

Work Step by Step

We need to get the b alone. Thus, we cancel out the addition by subtracting 11 on both sides. This leaves us with the equation $1/2b=-8$. b is being multiplied by a fraction, so we multiply by the reciprocal, 2/1, to get that b=-16. We plug -16 in for b and confirm that our answer is, indeed, correct.
