Answer
$b=\frac{55}{4}$
Work Step by Step
Step 1: $\frac{4}{5}b-5=6$
Step 2: Add 5 to both sides: $\frac{4}{5}b-5+5=6+5$.
Step 3: $\frac{4}{5}b=11$
Step 4: Multiply both sides by 5: $\frac{4}{5}b\times5=11\times5$.
Step 5: $4b=55$
Step 6: Divide both sides by 4: $\frac{4b}{4}=\frac{55}{4}$.
Step 7: $b=\frac{55}{4}$
