"System does not have a distinct solution" when solving system of linear equations #562

Closed CAG2Mark closed 3 years ago

CAG2Mark commented 4 years ago

nerdamer.solveEquations(['x+y=1', '2*x=6', '4*z+y=6']); outputs the following: [["x", 3], ["y", -2], ["z", 2]]

When I add the equation 'y = (-1) z' to the system, the solution should not change, as y is indeed equal to -z. However, when I run the following code: `nerdamer.solveEquations(['x+y=1', '2x=6', '4z+y=6', 'y = (-1) z']); I get the error: System does not have a distinct solution`

This one might be somewhat related to #546 but I'm not sure.

I don't know to be honest. But it would be useful if it was able to recognise duplicate equations in a system of linear equations.
