# Question #5ae16

$L = \frac{A - I}{Q}$

#### Explanation:

Please use the formatting! Writing formulas in words leads to ambiguity: you mean $Q = \frac{A - I}{L}$ or $Q = A - \frac{I}{L}$? I'll assume the first.

We start from $Q = \frac{A - I}{L}$.

Multiply the whole expression by $L$:

$Q \cdot L = \frac{A - I}{\cancel{L}} \cdot \cancel{L}$.

Divide both terms by $Q$:

$\frac{\cancel{Q} \cdot L}{\cancel{Q}} = \frac{A - I}{Q}$
