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.
Example 2×2 system
Solve: 1x + 1y = 1
1x – 2y = 3
