Answer:
6
Step-by-step explanation:
if F(x)=8 then that changes the equation to 8=x/2+5 meaning you need to make sure x/2+5 comes out to 8. What does five need to be added too to get 8? 3. So then you figure out what needs to be divided by two to get 3. Multiple 2 times 3 and you get 6. Making the equation
8 = 6/2 + 5
