Y = - x + 4, y = - 3x + 16. Answer as an ordered pair. (x, y)

Answer: Answer is (-3, 7)

Step-by-step explanation:

y = - x + 4 equ 1

y = 3x + 16 equ 2

Make x subject of formular in equ 1

x = 4 - y equ 3

Subatitute x = 4 - y in equ 2

y = 3 (4-y) + 16

y = 12 - 3y + 16

y + 3y = 12 + 16

4y = 28

y = 28/4 = 7

Substitute y = 7 in equ 1

7 = - x + 4

7 - 4 = - x

x = - 3

Answer is (-3, 7)

Set them equal to each other. - x + 4 = - 3x + 16 >>> (-x+3x) = (16-4) >>> 2x = 12 so x = 6. Plug in x to an equation. Y = - (6) + 4 so y = - 2. (6,-2) is the answer.
