x+2y=-2
2x-4y=0

multiply the first equation by 2
2x+4y=-4
add this to the first equation
2x+2x-4y+4y=0-4
add like terms
4x=-4
divide both sides by 4
x=-1
subtitue into 1st equation
-1+2y=-2
add 1 to both sides
2y=-1
divide both sides by 2
y=-1/2


another way is
since 2x-4y=0
so 2x must equal 4y
subtitue and get answer

1.Let's solve for x
.x+2y=−2
Step 1: Add -2y to both sides.
x+2y+−2y=−2+−2y
x=−2y−2
Answer:x=−2y−2

2.Let's solve for x.
2x−4y=0
Step 1: Add 4y to both sides.
2x−4y+4y=0+4y
2x=4y
Step 2: Divide both sides by 2.
2x/2=4y/2
x=2y
Answer:x=2y
