Question

solve the system equation:
2x-4y=-4
x+2y=8
PLEASE:(

Answer 1

multiply the bottom by -2, add the top and bottom together solve for y

Answer 2

multiply both sides of equation # 2 by 2 to get 2x+4y=16

Now add this equation to the first one to get 4x=12 and solve for x to get x = 3

Now plug this into either equation to find y

x+2y=8
3+2y=8
2y=5
y=5/2

Answer 3

THANKS!
