8-3b=-\frac{5}{2}\times 4
Multiply both sides by 4.
8-3b=\frac{-5\times 4}{2}
Express -\frac{5}{2}\times 4 as a single fraction.
8-3b=\frac{-20}{2}
Multiply -5 and 4 to get -20.
8-3b=-10
Divide -20 by 2 to get -10.
-3b=-10-8
Subtract 8 from both sides.
-3b=-18
Subtract 8 from -10 to get -18.
b=\frac{-18}{-3}
Divide both sides by -3.
b=6
Divide -18 by -3 to get 6.
