show that graphs of x-2x/x+2y=1/3 and x-y/x+y=3/5 coincide...how do you solve it?

I have a feeling you made a typ

did you mean (x-2x)/(x+2y)=1/3

then it would be -x/(x+2y) = 1/3

did mean x-2x/x+2y=1/3
then it would be x - 2 + 2y = 1/3

the second equation is equally confusing, please use brackets
