-4=\frac{-11\left(-4\right)}{5}+b
Express -\frac{11}{5}\left(-4\right) as a single fraction.
-4=\frac{44}{5}+b
Multiply -11 and -4 to get 44.
\frac{44}{5}+b=-4
Swap sides so that all variable terms are on the left hand side.
b=-4-\frac{44}{5}
Subtract \frac{44}{5} from both sides.
b=-\frac{20}{5}-\frac{44}{5}
Convert -4 to fraction -\frac{20}{5}.
b=\frac{-20-44}{5}
Since -\frac{20}{5} and \frac{44}{5} have the same denominator, subtract them by subtracting their numerators.
b=-\frac{64}{5}
Subtract 44 from -20 to get -64.
