For this case we have the following expression:
[tex] A = 2 (L + W)
[/tex]
From here, we want to clear the value of W.
For this, we follow the following steps:
1) Pass the number 2 dividing:
[tex] (L + W) = \frac{A}{2}
[/tex]
2) Pass the variable L subtracting:
[tex] W = \frac{A}{2} - L
[/tex]
Thus, we observe that we have the equation solved for the variable W.
Answer:
Solving the equation for W we have:
[tex] W = \frac{A}{2} - L [/tex]
