System of linear equations solver solves systems of linear equations. You choose from 2×2 or 3×3 systems. Notes: • x, y, and z results are automatically stored in the x, y, and z variables. • Use r to toggle the results (x, y and z) as needed. • The 2x2 equation solver solves for a unique solution or displays a message indicating an infinite number of solutions or no solution. • The 3x3 system solver solves for a unique solution or infinite solutions in closed form, or it indicates no solution.

Notes:
•
x, y, and z results are automatically stored in the x, y, and z
variables.
•
Use
r
to toggle the results (x, y and z) as needed.
•
The 2x2 equation solver solves for a unique solution or
displays a message indicating an infinite number of
solutions or no solution.
•
The 3x3 system solver solves for a unique solution or
infinite solutions in closed form, or it indicates no solution.
