## Addition solving with n unknown

 Solving Domain Set Reals numbers (fractions or decimal places, etc.) Integers numbers

Tool to solve an addition equation with one or more unknowns. Specialized equation solver for additions with one or more variables.

### How to solve an addition with dCode?

The addition solving uses the equation solver available on dCode. This is a special form of equation involving the + addition operator.

Example: Equation with 1 variable $$1+x=2 \iff x=1$$

Example: Equation with 2 variables $$x+y=0 \iff x=-y$$

Indicate the variable with a letter (generally x) and to indicate that it is this unknown which is sought, the solver will give the addition result either in the form of integer if it exists, either in form of fraction, or in numerical form (number with decimal places).

### How to solve a system with multiple additions?

Indicate several lines of addition with the same variable(s). An alternative solution is to separate them with the AND logical operator: &&.

### How to solve other types of equations?

Equations involving subtraction, multiplication, division etc. can be solved via the dCode equation solver.
