Answer:
Alright this is complecated but I think you can go on this other math website symbolab there will be a tutor and answer it in 15-30 minuted it helps!
Step-by-step explanation:
I believe that x=4 would be the answer
Write f(x) / g(x) = 1 / ((x+1)(x-2)).
It's easy to see that x cannot be -1 and 2;
So all real numbers exclude -1 and 2, which matches the second choice.
X + y = 10
x - y = 2
add the equations together
2x = 12
x = 6
6 + y = 10
y = 3
