You can put this solution on YOUR website!
Note: you can type root(3,x+y) to mean root%283%2Cx%2By%29


root%283%2C2x%29=root%283%2C5x%2B2%29 ... Start with the given equation.

%28root%283%2C2x%29%29%5E3=%28root%283%2C5x%2B2%29%29%5E3 ... cube both sides

2x+=+5x%2B2 ... cube the cube roots (notice they cancel out)

I'm sure you know what to do from here.
