Hi,

Needs["Graphics`ImplicitPlot`"]

eqn1 = x + y == 2*x*y;
ImplicitPlot[eqn1, {x, 1, 3}, {y, 0, 2}]

or

f = y /. Solve[eqn1, y][[1]]
Plot[Evaluate[f], {x, 1, 3}]

Regards

  Jens

| Hello
|
| Can anyone tell why this is wrong?
|
| eqn1 = x + y == 2*x*y;
| eqn1 /.y -> y[x];
| Plot[y[x], {x, 1, 3}]
|
| How do I do it correctly? (This is just an 
example; I want to do this
| with a much more difficult equation)
| Thanks a lot.
