A) $\frac { - 2 } { x - 7 }$
B) $\frac { 6 } { x - 7 }$
C) $\frac { 8 } { x - 7 }$
D) $\frac { 2 } { x - 7 }$

Quizplus · Accepted Answer

The key is to recognize that $7 - x$ is the same as $-(x - 7)$. Therefore, $\frac{4}{7-x} = \frac{4}{-(x-7)} = -\frac{4}{x-7}$. Adding $\frac{2}{x-7}$ and $-\frac{4}{x-7}$ gives $\frac{-2}{x-7}$.
