SUMMARY

The nonlinear equations 3xy - 2xz = -1, -xy - xz = -1, and -2xy + 3xz = 2 can be solved by substituting variables, specifically letting a = xy and b = xz, which transforms the system into a linear one. Factoring out x reveals that y = 1/(5x) and z = 4/(5x), indicating an infinite number of solutions due to the dependence of the equations. One equation can be expressed as a linear combination of the others, confirming the system's redundancy.

Substitute a=xy and b=xz and solve the linear system.

Another way you can do it is by factoring out x.
 
It is giving you a solution,
<br /> y=\frac{1}{5x}\qquad z=\frac{4}{5x}<br />
In fact that is an infinite number of solutions, since x is just a free-parameter. You get this because not all of your equations are independent. In other words, one of the equations can be written as a linear combination of the other two.
