7. 11h - (2h - 1) = 118

Explanation:

Step1: Remove parentheses

$11h - 2h+1 = 118$

Step2: Combine like - terms

$(11h - 2h)+1 = 118$, so $9h+1 = 118$

Step3: Subtract 1 from both sides

$9h+1 - 1=118 - 1$, which gives $9h = 117$

Step4: Divide both sides by 9

$\frac{9h}{9}=\frac{117}{9}$, so $h = 13$

Answer:

$h = 13$
