Do not use x which is a letter, so a variable, instead use the symbol * or the multiplication cross ×, nothing else.

Example: $ x*2=10 \iff x=5 $

Indicate the variable with a letter (like x or y, do not use ?) and note it as unknown, the solver will give the subtraction result either in the form of integer, of fraction, or in numerical form.

How to solve a system with multiple multiplications?

Indicate several lines of equations based on multiplications with the same variable(s). Or, separate the multiplications with the AND logical operator: &&.

How to read a multiplication?

The sign of multiplication can be read times or 'multiplied', it is sometimes implied and therefore omitted.

Example:5y for 5 times y
