dCode is free and its tools are a valuable help in games, maths, geocaching, puzzles and problems to solve every day! A suggestion ? a feedback ? a bug ? an idea ? Write to dCode!

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