3 0

X=5+y

Substitute the value of x in second equation
28x – 9y= -12
28 (5+y)-9y =-12
140 +28y -9y =-12
140 +19y= -12
19y = - 152
y= -8

Now let's find the value of x using y

x= 5+y
x= 5 + (-8)
= -3

So,
x= -3
y=-8

Paraphin [41]

To answer this equation, firs you must assign the g(x) to the value of f(x) to make the function answerable and able to find the value of x. So its gonna be f(g(x)) = 4(4x)-32. So x = 2 and f(x) = -24 and g(x) = 8
