# solve() Function Returns Input Equations

When solving for a system of 5 equations with 5 variables, the solve() function returns the exact functions I input. Is this indicative of an issue? Or is there another way to solve for a system of equations if I encounter this error?

The

`solve`

function does that when it is unable to solve.Sometimes,

`solve(equations, variables, to_poly_solve=True)`

can help.For polynomial equations, one can define an ideal in a polynomial ring and compute its variety.

Providing a minimal example illustrating the problem might inspire more relevant answers.
