Question #4995

-4x-2y=-12
4x+8y=-24

Expert's answer

At first let's add equations :& -4x-2y+4x+8y=-12-24

Hence 6y=-36 => y=-6

Then using the second equation of the system we obtain& 4x+8(-6)=-24

4x-48=-24

4x=24

Hence x=6

So the answer is x=6, y=-6

Hence 6y=-36 => y=-6

Then using the second equation of the system we obtain& 4x+8(-6)=-24

4x-48=-24

4x=24

Hence x=6

So the answer is x=6, y=-6
