C. -10

(20+2x)/(5-x)
Multiply both sides by lowest common denominator, simplify
\frac{(5-x)(20+2x)}{5-x} = (5-x)0

2x + 20 = 0

2(x + 10) = 0
factor out 2 from 2x+20

Answer:

11+7x

Step-by-step explanation:

Simplifying

9x + 10 + -2x + 1

Combine like terms: 9x + -2x = 7x

11 + 7x

Final result:

11 + 7x
