Solve for m. 2(m + 2) = 20 m = _____

Distribute 2: Step 1: Distribute the 2 to both terms inside the parentheses. Calculation: 2(m + 2) = 2m + 4.Set up equation: Step 2: Set up the equation to solve for m. Calculation: 2m + 4 = 20.Subtract to isolate: Step 3: Subtract 4 from both sides to isolate the term with m. Calculation: 2m + 4 - 4 = 20 - 4, which simplifies to 2m = 16.Divide to solve: Step 4: Divide both sides by 2 to solve for m. Calculation: 2m / 2 = 16 / 2, which simplifies to m = 8.

Distribute $2$ : Step $1$ : Distribute the $2$ to both terms inside the parentheses. $\newline$ Calculation: $2(m + 2) = 2m + 4$ .
Set up equation: Step $2$ : Set up the equation to solve for $m$ . $\newline$ Calculation: $2m + 4 = 20$ .
Subtract to isolate: Step $3$ : Subtract $4$ from both sides to isolate the term with $m$ . $\newline$ Calculation: $2m + 4 - 4 = 20 - 4$ , which simplifies to $2m = 16$ .
Divide to solve: Step $4$ : Divide both sides by $2$ to solve for $m$ . $\newline$ Calculation: $\frac{2m}{2} = \frac{16}{2}$ , which simplifies to $m = 8$ .
