Which ordered pair is the solution to the system of equations?

2x+4=-8

x-y=-4

A.

(-3, - 2)

B.

(-1, 3)

C.

(1, 5)

D.

(-4, 0)

2x+y=-8 | x-y=-4

You can solve this system in two ways: multiplying the second equation by 2 and subtracting it, or isolating one of the variables in either equation and substituting. I'm going to isolate one of the variables and substitute, but f you want to see the other way, just notify me.

2x+y=-8 | x=y-42

(y-4) + y=-82

y-8+y=-8

y=0

Then substitute y in one of the equations.

x-0=-4

x=-4

Therefore, the correct answer is D. (-4,0)
