4x + 3y = 54 (1)
3x + 9y = 108 (2)
Multiply (1) by (-3)
-12x - 9y = -162
3x + 9y = 108
---------------------add
-9x = -54
x = 6
plug x = 6 into (1) to find y
4(6) + 3y = 54
24 + 3y = 54
3y = 30
y = 10
Answer
(6 , 10)

Answer:
8x - 7.
Step-by-step explanation:
f(x) = 2x - 5,
g(x) = 4x -1,
substituting g(x) as x in f(x),
f(g(x)) = 2(4x - 1) - 5
= 8x - 7
