Step-by-step explanation:
Hey there!
Given;
f ( x ) = x² + 2x - 1
g ( x ) = 3x - 2
To verify:

LHS:

~ Insert "2" instead of "x".

Simplify it;

Therefore; (f/g)(2) = 7/4.
RHS:

~Insert "2" instead of"x".

Simplify it.

Therefore, f(2)/g(2) = 7/4.
Since (f/g)(2) = f(2)/g(2) = 7/4.

Uhh, these give me a headache, I think number 2 is array..
X = -6y - 12
4x + 5y =-39
4x + 5y = -39
-4(-6y - 12) + 5y = -39
-4(-6y) + 4(12) + 5y = -39
24y + 48 + 5y = -39
29y + 48 = -39
29y = -87
y = -3
x = -6y - 12
x = -6(-3) - 12
x = 28 - 12
x = 6
(x, y) = (6, -3)

pemdas
x=2 and y = 6 for your awnser hope it helped
