You can put this solution on YOUR website!
Can't be done.
To solve for three equations, you need three independent equations.
With only two, you can get a variable in terms of the other variables.
As in this case,
4x%2B4y=2xy
4x-2xy=-4y
x%284-2y%29=-4y
highlight%28x=2y%2F%28y-2%29%29
So now you have an equation for x and for z in terms of y.
But that's the best you can do.
