What is the value of 6x if 3 (x – 4) + x = -2?

15

Step-by-step explanation:

3 ( x - 4) + x = -2

3x - 12 + x = -2

4x - 12 = -2

4x = 10

x = 2.5

6(2.5) = 15  

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
