Answer:

x = 4.

Step-by-step explanation:

f(2) = 3(2) - 1 = 5.

So  2x - 3 = 5

2x = 5 + 3

x = 8/2 = 4 (answer).

Answer:

g(x) =f(2)  when x=4

Step-by-step explanation:

First step is to find f(2)

f(2) is when x=2

f(2) = 3(2) -1

f(2) = 6-1

f(2) = 5

We want to find x when g(x) =5

g(x) = 2x-3

5 = 2x-3

Add 3 to each side

5+3 = 2x-3+3

8 = 2x

Divide each side by 2

8/2 = 2x/2

4 = x
