Question

If f(x) = 3x+5 solve for x when f(x) = 11

Answer 1

x=2

Explanation:

f(x)=3x+5

11=3x+5

11-5=3x

6=3x

x=6

3

x=2

hope it helps.

Answer 2

2

Explanation:

It is saying that both equations equal each other, as they both equal f(x). So we just move each of the factors to equal each other. Like 3x+5=11. There you just subtract the 5 from both sides to get 3x=6, and then divide both sides by 3 to get x=2.
