15 = ½ (7x-6)
distribute ½ into parentheses
15 = ½(7x) - ½(6)
15 = ⁷/₂x - 3
multiply by 2
30 = 7x -6
subtract +6 to both side
30 + 6 = 7x
36 = 7x
devide 7 to both side
36
------ = x

Answer:
(f -g)(2) = 14
Step-by-step explanation:
You can write the expression for the composite function as ...
(f -g)(x) = f(x) -g(x) = (3x² +1) -(1 -x)
(f -g)(x) = 3x² +x
Then for x = 2 ...
(f -g)(2) = 3(2²) +2
(f -g)(2) = 14
