Pre-Algebra Examples

$\frac{5 - x}{x - 5}$

Step 1

Rewrite $5$ as $- 1 (- 5)$ .

$\frac{- 1 (- 5) - x}{x - 5}$

Step 2

Factor $- 1$ out of $- x$ .

$\frac{- 1 (- 5) - (x)}{x - 5}$

Step 3

Factor $- 1$ out of $- 1 (- 5) - (x)$ .

$\frac{- 1 (- 5 + x)}{x - 5}$

Step 4

Reorder terms.

$\frac{- 1 (x - 5)}{x - 5}$

Step 5

Cancel the common factor.

$\frac{- 1 (x - 5)}{x - 5}$

Step 6

Divide $- 1$ by $1$ .

$- 1$

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
