The given equation to us is ,
x/2= 3
x = 3*2
x = 6
Now we need to find out ,
2x + 2
2(6) + 2
12 + 2
14
<u>Hence </u><u>the</u><u> required</u><u> answer</u><u> is</u><u> </u><u>1</u><u>4</u><u>.</u>

Answer:
17
Step-by-step explanation:
I would just solve them individually for 3 and then add them together. f(x)=6(3)+3 = 21 and g(x)= 3-7= -4
(f+g)(3) = 21-4= 17
