Hi there!

[tex]\large\boxed{x = -5}[/tex]

Find the value of 8 by substituting in -18 for g(x):

-18 = 2x - 8

Add 8 to both sides:

-10 = 2x

Divide both sides by 2:

-10/2 = 2x/2

x = -5

Substitute g(x) = -18 in g(x) = 2x-8

[tex] - 18 = 2x - 8 \\ 2x - 8 = - 18 \\ 2x = - 18 + 8 \\ 2x = - 10 \\ x = - 5[/tex]

Thus, x = -5 when g(x) = -18
