Solving systems of equations

Systems of equations Sistemi di equazioni

This calculater solves a system of two equations.
Enter the equations you want to solve.




How do you want the system of equations to be solved?
Equalize the equations.
Insert one equation into the other one.
Add the equations.


If your system consists of more than two equations, enter them in here.



A system of linear equations consists of multiple linear equations. Linear equations with two variables correspond to lines in the coordinate plane, so this linear equation system is nothing more than asking if, and if yes, where the two lines intersect. This implies it can have no solution (if the lines are parallel), one solution (if they intersect) or infinitely many solutions (if the lines are equal).

There are three important ways to solve such systems: by insertion, by equalization and by adding.

Equalization means you solve both equations for the same variable and then equalize them. This means, one variable remains and the calculation is then easy.
