# Two equations System

Solve two linear equations system with two unknowns x and y :

`{(a*x,+,b*y,=,c),(d*x,+,e*y,=,f):}`

`{(a*x,+,b*y,=,c),(d*x,+,e*y,=,f):}`

## How to use this calculator ?

This calculator is a two linear equations System with two unknowns Solver.It calculates the exact solutions when they exist and also gives a numerical approximation of them.

### Coefficients input

Here are some hints to help you enter the coefficients of the equations.- Accepted inputs are,
- integers, example: 5, -7
- fractions, example: 1/3 or -2/9
- decimal values, example: 3.9 or -9.65
- constants, example: pi or e
- common functions, for example: sin(pi/5)
- square root operator, example : input sqrt(3) or 3^0.5 for `sqrt(3)`
- complex numbers, example : 1+i ou -i

- To enter a product of two factors, use the * operator. For example: enter 2*pi and not 2pi.
