Linearity is an app that solves systems of linear equations in matrix form.

- Solve up to 8 simultaneous linear equations.

- Data entry is easy with the matrix view and large buttons.

- Linearity tells you if there is no solution or if two or more equations are linearly dependent.

If you are not familiar with the matrix form of systems of linear equations, here is an example.

This system of 2 equations:

2x+y=3

x-3y=1

Is represented in matrix form as:

[2][1][3]

[1][-3][1]

Each row represents an equation. The row entries are the magnitudes of each term. Make sure each equation has the variables in the same order, and that you insert a zero for a variable that does not appear in the equation.
