Solve for n. 4(n + 2) = 20 n = _____

Distribute 4: Step 1: Distribute the 4 into the parentheses. Calculation: 4(n + 2) = 4n + 8.Solve for n: Step 2: Solve for n by isolating it on one side of the equation. Calculation: 4n + 8 = 20; 4n = 20 - 8; 4n = 12.Divide by 4: Step 3: Divide both sides by 4 to find n. Calculation: n = 12 / 4; n = 3.

Distribute $4$ : Step $1$ : Distribute the $4$ into the parentheses. $\newline$ Calculation: $4(n + 2) = 4n + 8$ .
Solve for n: Step $2$ : Solve for $n$ by isolating it on one side of the equation. $\newline$ Calculation: $4n + 8 = 20$ ; $4n = 20 - 8$ ; $4n = 12$ .
Divide by $4$ : Step $3$ : Divide both sides by $4$ to find $n$ . $\newline$ Calculation: $n = \frac{12}{4}; n = 3$ .
