Answer:
y=4,x=1
Step-by-step explanation:
4x+y=8
x+y=5
subtract equation 2 from equation 1
3x + 0=3
3x=3
divide both sides by 3
x=1
substitute for x=1 in equation 2
x+y=5
1+y=5
y=5-1(collecting like terms)
y=4

Answer:
- g(x) = x^2 +2
- f(g(x)) = 1/(x^2 -3)
Step-by-step explanation:
A. g(x) is given:
g(x) = x^2 +2
__
B. f(g(x)) = f(x^2 +2) = 1/((x^2 +2) -5) . . . . substitute for g(x) and simplify
f(g(x)) = 1/(x^2 -3)
