Final answer:

To find x when y = 20, substitute y with 20 in the equation g(x) = 3x + 8 and solve for x.

Step-by-step explanation:

The equation given is g(x) = 3x + 8. We need to find the value of x when y = 20. To do this, we substitute y with 20 in the equation and solve for x.

20 = 3x + 8

Subtract 8 from both sides to isolate the term with x: 20 - 8 = 3x

Now, simplify the equation: 12 = 3x

Finally, divide both sides by 3 to solve for x: 12/3 = x

Therefore, x = 4.
