Basic Math Examples

$\frac{4 n - 7}{7 - 4 n}$

Step 1

Factor $- 1$ out of $4 n$ .

$\frac{- (- 4 n) - 7}{7 - 4 n}$

Step 2

Rewrite $- 7$ as $- 1 (7)$ .

$\frac{- (- 4 n) - 1 (7)}{7 - 4 n}$

Step 3

Factor $- 1$ out of $- (- 4 n) - 1 (7)$ .

$\frac{- (- 4 n + 7)}{7 - 4 n}$

Step 4

Rewrite $- (- 4 n + 7)$ as $- 1 (- 4 n + 7)$ .

$\frac{- 1 (- 4 n + 7)}{7 - 4 n}$

Step 5

Reorder terms.

$\frac{- 1 (- 4 n + 7)}{- 4 n + 7}$

Step 6

Cancel the common factor.

$\frac{- 1 (- 4 n + 7)}{- 4 n + 7}$

Step 7

Divide $- 1$ by $1$ .

$- 1$
