Question

How to solve for "W" in this equation: A=2(L+W)

Answer 1

$A=2(L+W)\\\\A=2 L+2W\\ \\2W=A-2L\ \ /:2 \\\\W=\frac{A}{2} -\frac{2L}{2}\\\\W=\frac{1}{2}A -L$

Answer 2

For this case we have the following expression:

$A = 2 (L + W)$

From here, we want to clear the value of W.

For this, we follow the following steps:

1) Pass the number 2 dividing:

$(L + W) = \frac{A}{2}$

2) Pass the variable L subtracting:

$W = \frac{A}{2} - L$

Thus, we observe that we have the equation solved for the variable W.

Answer:

Solving the equation for W we have:

$W = \frac{A}{2} - L$
