You can put this solution on YOUR website!
2x%2B6y=0, EQN 1
-2x-5y=0, EQN 2
In EQN 1:
-2x=6y ---->cross%28-2%29x%2Fcross%28-2%29=cross%286%293y%2Fcross%28-2%29
x=-3y, subst. in EQN 2:
-2%28-3y%29-5y=0
6y-5y=0
highlight%28y=0%29, subst. in EQN 1:
2x%2B6%2A0=0
2x=0
highlight%28x=0%29
We'll see the graph:

---> RED >>> 2x%2B6y=0; GREEN >>>> -2x-5y=0
.
Thank you,
