Answer:

(7 -7)

Step-by-step explanation:

Y= -4x +5-----------1

Y= 3x -16----------2

Y-5= 4x

X= (y-5)/4

Substitute in (eqn 2)

( tired )

The solution to the system of equations y = -4x + 5 and y = 3x - 16 is x = 3 and y = -7

Given the system of equations:

y = -4x + 5   (1)

y = 3x - 16    (2)

Substitute y = -4x + 5 in equation 2:

-4x + 5 = 3x - 16

7x = 21

x = 3

Put x = 3 in y = -4x + 5:

y = -4(3) + 5

y = -7

The solution to the system of equations y = -4x + 5 and y = 3x - 16 is x = 3 and y = -7
