The solve_system function allows to solve equations with several unknowns: Equation 2 unknown systems, systems of equations with 3 unknown in n unknowns systems.

Solve_system online

**Solving equations with several unknowns** in other words, **solving system of equations online**
is possible through the use of the function solve_system of the calculator.
The calculator allows the **resolution system online** of several types, it is possible :

- to
**solve systems of equations with two unknown online**, - to
**solve systems of equations with three unknowns online**, - and more generally, the
**resolution of online systems equation**with several unknowns.

With its ability to algebra, the calculator can **solve equations with two unknown** or **solve equations with 3 unknowns** involving letters (literal calculation).

The calculator is a solver of equations system that uses a very simple syntax .

For example, to **solve online the following system** x+y=18 and 3*y+2*x=46, enter
solve_system([x+y=18;3*y+2*x=46];[x;y]) , after calculation, the result [x=8;y=10] is returned.

The solve_system function allows to solve equations with several unknowns: Equation 2 unknown systems, systems of equations with 3 unknown in n unknowns systems.

- x+y=18
- 3*y+2*x=46
