Equation Solver

dCode can solve equations and find variables. The equations must contain a comparison character such as equal, ie. = (or < or >).

Example: 2x=1 returns for solution x=1/2

dCode returns exact solutions (integers, fraction, etc.) by default, if the equation contains comma numbers then dCode will return a solution with decimal numbers.

Example: 2x=1.0 returns for solution x=0.5

To solve a cryptarithm (replacing letters with multiple values between 0 and 9), use the dCode cryptarithm solver.

Equations can be combined with the and (logical conjunction) operator : && or ⋀ or with a line return between each equation.

Example: 2x+1 = 3 && 3x-1 = 2 gives x=1

Equations have to be separated with && or ⋀. Variables have to be listed and separated in the variables input box.

The calculation steps of the solver are not shown because they do not correspond to the steps a human would make. The operations performed by the solver are binary calculations bit by bit very different from those of a resolution by hand from a mathematician.
