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
