# How do you solve A=LW for L?

Mar 14, 2018

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

#### Explanation:

To solve an equation for a variable, in this case L, you need to isolate the variable on one side of the equation with the other terms on the other side. For multiplication of variables, you simply divide both sides of the equation by the variable you are not trying to find in order to isolate the variable you want:

$A = L W$

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

$\frac{A}{W} = L \cdot 1$

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