Question

Let f(x) = -5x - 4 and g(x) = 6x - 7. Find f(x) + g(x)

Answer 1

x - 11

Explanation:

Substitute the given equations for f and g, then combine like terms.

f(x) = = –5x – 4 and g(x) = 6x – 7

Find f(x) + g(x).

(-5x - 4) + (6x - 7) =

-5x - 4 + 6x - 7 = (Combine like terms here.)

6x - 5x -7 -4 = (Simplify.)

x - 11

Answer 2

-5x-4+6x-7= 0
-5x+6x-4-7=0
x-11=0
x=11
