Answer
$h=16$
Work Step by Step
Step 1: $\frac{3}{8}h+7=13$
Step 2: Subtract 7 from both sides: $\frac{3}{8}h+7-7=13-7$.
Step 3: $\frac{3}{8}h=6$
Step 4: Multiply both sides by 8: $\frac{3}{8}h\times8=6\times8$.
Step 5: $3h=48$
Step 6: Divide both sides by 3: $\frac{3h}{3}=\frac{48}{3}$.
Step 7: $h=16$
