Question

Line A: y = x − 2
Line B: y = 3x + 4

Which of the following shows the solution to the system of equations and explains why?

Answer 1

Step-by-step explanation:

y = x -2 —(1)

y= 3x + 4 — (2)

(2) - (1)

0 = 3x + 4 -x + 2

=> 2x = -6

=> x = -3

y = x-2 = -5

Answer 2

Answer:

x = -3 and y = -5

on proof you can see for first line

-5 = -3 - 2

-5=-5

for second line

-5 = 3(-3)+4

-5 = -9+4

-5 = -5
