1.) 7x - 9 = -4x + 90
7x +9. = -4x. + 9
7x. = -4x. 99
+4x = +4x. + 99
11× = 99
÷ 11. ÷ 11
X = 9

I believe your answer is:

$g(3) = -8$

Here’s why:

⸻⸻⸻⸻

$\boxed{\text{Evaluating the function...}}\\\\g(x)=-4x+4; g(3)\\\\--------------\\\rightarrow g(3)=-4(3)+4\\\\\rightarrow g(3) = -12 + 4\\\\\rightarrow \boxed{g(3)=-8}$
