Let f%28x%29+=+-5x+-4 and g%28x%29+=+6x+-7.
Find f%28x%29+%2B+g%28x%29

f%28x%29+%2B+g%28x%29=%28-5x+-4%29%2B%286x+-7%29

f%28x%29+%2B+g%28x%29=-5x-4%2B6x+-7%29

f%28x%29+%2B+g%28x%29=+%286x-5x%29%2B%28-4+-7%29

f%28x%29+%2B+g%28x%29=+x-11

so, answer is:

C. x+-+11

f(x) = -5x - 4 and
g(x) = 6x - 7
x - 11 = f(x) + g(x)
