Equation Solver

List the polynomial’s coefficients from the highest power down to the constant term, writing a zero for every missing power.

Example: 1, 0, -4 stands for x² − 4, and 1, -3, 2 for x² − 3x + 2.

The coefficients on the left-hand side of the system: one row per equation, one number per unknown.

For 2x + y = 5 and x + 3y = 10 enter 2, 1 on the first line and 1, 3 on the second.

The constants on the right-hand side, one per equation, in the same order as the rows of A.

For the system above that is 5, 10.
