# Subtraction with Unknown(s)

## Subtraction solving with n unknown

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

### How to solve a subtraction/difference equation with dCode?

The calculation of a subtraction or a difference is based on the dCode equation solver. This is only a particular form of equation involving the - subtraction operator (minus).

Example: $x-2=1 \iff x=3$

Indicate the equation variable with a letter (often x, avoid ?) and to indicate that it is this unknown which is sought, the solver will return the subtraction result either as an integer, fraction, or a floating point number (numeric form).

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

Indicate several lines of subtractions with the same variable(s) or eventually link them with the AND logical operator: &&.

Example: x - 1 = 0 && y + 1 = 0

### How to solve other types of equations?

Equations involving addition, multiplication, division or others can be solved by the dCode equation solver.

### How to read a subtraction?

The subtraction sign is read minus or subtracted.

Example: 5-z is read 5 minus z or z subtracts from 5
