Answer:
x=-2 and y=-3
Step-by-step explanation:
2x+4y=-16
-2(-2x+2y=-2)
2x+4y=-16
4x-4y=4
6x=-12
x=-2
2x+4y=-16
2(-2)+4y=-16
-4+4y=-16
+4 +4
4y=-12
y=-3
Answer:
x=-2
y=-3
Step-by-step explanation:
2x=-4y-16 subtract 4y and move to the other side of the equation
x=-2y-8 divide by 2 to isolate x
-2(-2y-8)+2y=-2 plug x into the second equation
4y+16+2y=-2 distribute
6y=-18 combine the Y's and subtract 16 to the other side
y=-3 divide both sides by 6
2x+4(-3)=-16 plug the y value into the first equation to find x
2x-12=-16 distribute (multiply)
2x=-4 add 12 to both sides
x=-2 divide by 2 to get the x value
