i have three complex nonlinear equations with four unknowns and want the plot of two unknowns as a simple example think of these equations:
5*sqrt(a*x)-sin(x)=0
b*sin(x)-x=0
sin(a*x)-1/(b*x*y)=0
and i want curve of y versus x
sorry for my bad english

in fact there are four unknowns: a, b, x, y for a specific x it become three equation with three unknowns which can be solved. so we find corresponding y. but question is how to plot y versus x?
