Which of the following has a solution of (-2, 1)

y=-2x-2 and 2x-2y=5
2x-y=-5 and x+2y=10
x-4y=8 and 3x +10=-2y
y=-3over2x -2 and 2x -y=-5

1 answer

The first equation has a solution of (-2, 1).

y = -2x - 2 and 2x - 2y = 5

Step 1: Substitute x = -2 into y = -2x - 2
y = -2(-2) - 2
y = 4 - 2
y = 2

Therefore, the solution of the first equation is (-2, 1).
