# How do you solve for s in D = C - s / n?

Aug 3, 2015

$s = \left(C - D\right) \cdot n$

#### Explanation:

First we have to move expression with $s$ to left side, and expressions without $s$ to the right side:

After first move we get:

$\frac{s}{n} + D = C$ - moved $\left(- \frac{s}{n}\right)$ left

$\frac{s}{n} = C - D$ - moved $D$ right

Last step is multiplying both sides by $n$

$s = \left(C - D\right) \cdot n$
