?

\newline

Choose

1

answer:

Write Equation: Write down the given equation. $\newline$ We have the equation $\ell = 2(w + 1)$ .
Distribute $2$ : Distribute the $2$ to both terms inside the parentheses. $\newline$ $\ell = 2w + 2$
Isolate $w$ : Isolate $w$ on one side of the equation. $\newline$ To do this, we need to subtract $2$ from both sides of the equation. $\newline$ $\ell - 2 = 2w + 2 - 2$
Simplify: Simplify the equation. $\ell - 2 = 2w$
Divide and Solve: Divide both sides of the equation by $2$ to solve for $w$ . $\frac{\ell - 2}{2} = \frac{2w}{2}$
Final Expression: Simplify the equation to get the final expression for $w$ . $w = \frac{\ell - 2}{2}$
