Answer:

f(7) = 2

Step-by-step explanation:

3f(7) + f(7)g(7) = 18

3f(7) + f(7)(6) = 18

f(7) (3 + 6) = 18

f(7) x (9) = 18

f(7) = 2

F(7) = 2

Explanation:
It gives you the limit as x goes to 7 of an expression. Try to plug in x = 7, and set it equal to the right hand side.
3f(7) + f(7)g(7) = 18
We can replace g(7) with 6
3f(7) + 6f(7) = 18
9f(7) = 18
f(7) = 2
