Answer:
[tex]\huge\boxed{\bf{x = 10}}[/tex]
Step-by-step explanation:
[tex] \sf g(n) = 10n - 10 \Rightarrow g(x) = 90[/tex]
Let's find x
[tex]\sf \to g(x) = 90[/tex]
$\sf \to 10x - 10 = 90$
$\sf \to 10x - 10 + 10 = 90 + 10$
$\sf \to 10x + 0 = 100$
$\sf \to 10x = 100$
$\sf \to x = \frac{100}{10}$
$\sf \to x = 10$
