Answers to Questions

How to solve an equation?

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

x-2=0 returns x=2

If you try to solve a cryptarithm (multiple values between 0 and 9), you should use the cryptarithm solver.

How to solve multiple equations?

Equations can be combined with the and (logical conjunction) operator : && or ⋀.

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

How to solve multiple equations with multiple variables?

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

How to solve an equation step by step?

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 and do not match the expected steps of resolutions of a human approach.
