System of Equations Calculator

This solver handles linear systems of two equations in x and y, or three equations in x, y and z. You type each coefficient and each constant into its own box rather than typing the equations as text, and it runs Gaussian elimination with partial pivoting to find the values that satisfy every equation at once. Alongside the answer it restates the equations as you entered them and reports the determinant of the coefficient matrix. When that determinant is zero there is no single solution, and the tool says so instead of returning a number; nonlinear systems are not supported.
