About the Systems of Equations Solver
This calculator solves systems of 2 or 3 linear equations using Cramer's Rule with detailed step-by-step solutions. For 2x2 systems, it also graphs both lines and shows the intersection point.
Features
- Solve 2x2 and 3x3 systems of linear equations
- Detects unique solutions, infinite solutions, and no-solution cases
- Step-by-step solution using Cramer's Rule
- Verification of the solution by substitution
- Interactive graph for 2x2 systems showing intersection
- Quick preset examples for common systems
Methods Used
- Cramer's Rule: Uses determinants to solve the system directly
- Determinant check: If D=0, checks for dependent or inconsistent system
- Graphical: 2x2 systems visualized as intersecting lines
