ezplot system of three nonlinear eqations by four unknows

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

Is the @ a typo? What should it be?

sorry, it was mistype!

and are a and b constants? what are their values?

Answer 1

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?
