Is there any more to the problem?
Answer: 20
Step-by-step explanation:
Assuming g(x) = -4x + 1,
( -4 (-4) + 1) - (-4 + 1)
= (16 + 1) - (-3)
= 17 + 3
= 20
5x+4y = 73
-4x + 4y = -8
5x + 4y -(-4x+4y) = 73 -(-8)
5x + 4y + 4x - 4y = 81
5x + 4x + 4y - 4y = 81
9x = 81
x = 81÷9
x = 9
Substitute x = 9 into any of the equations to find y.
5(9) + 4y = 73
45 + 4y = 73
4y = 73 - 45
4y = 28
y = 28÷4
y=7
