solve for r.\n-14 = 4 - (r + 8)\nr =

Explanation:

Step1: Remove parentheses

$$ \begin{align*} -14&=4 - r - 8\ -14&=-r - 4 \end{align*} $$

Step2: Add (r) to both sides

$$ \begin{align*} -14+r&=-r - 4+r\ r - 14&=- 4 \end{align*} $$

Step3: Add 14 to both sides

$$ \begin{align*} r-14 + 14&=-4+14\ r&=10 \end{align*} $$
