Equation Solver

An equation is a mathematical equality between two expressions separated by an equal sign =. Each of these expressions can contain numbers, variables (called unknowns), or operations.

The dCode calculator allows you to solve equations (and also inequalities) to find their unknowns. An equation must contain a comparison sign, usually = (or < or >).

dCode returns exact solutions (integers, fraction, etc.) by default (for linear and nonlinear equation systems), if the equation contains floating point numbers. then dCode will return a solution with decimal numbers.

To solve multiple equations at the same time (a system of equations), separate them with the logical operator && or ⋀, or place each equation on a separate line.

To solve a system of equations, the solver expects each equation to be on a new line or on a single line but separated by && or ⋀. Then enter the unknowns to be found in the field provided.

Use the dedicated tool to check an equality or else, enter the equation and click on solve, the solver will answer true if the equality is checked whatever the variable (there are an infinite number of possible solutions for the variable).

The solver will return false if equality is not possible (if there is no solution for the variable)

To restrict the search for solutions to a particular domain, add an additional condition after the equation.

The solver doesn't show the steps because, like a calculator, it displays the result directly without going through the manual developments. It uses internal mathematical shortcuts, and the intermediate steps simply don't exist in its calculation mode.
