Using the graph, the point of intersection appears to be {0,0}.
Check to see if {0,0} satisfies the system of equations
y+2*x=0
x+2*y=0
Replace x and y with x=0 and y=0 in the two equations.
0+2*0 = 0
0+2*0 = 0
So the point {0,0} satifies the system of equations and it is a solution.
I hope that this helps.
