System Solver
Enter two equations as a1x + b1y = c1 and a2x + b2y = c2. The solver classifies the system, shows elimination steps, and graphs both lines.
1 System Solver
Type the six coefficients. The solver computes the determinant, classifies the system, eliminates step by step, and draws the graph.
Input: a1x + b1y = c1, a2x + b2y = c2
Solution
Press Solve the system.
Blue: equation 1 · teal: equation 2 · gold: the solution.
2 The determinant decides
D = a1b2 − a2b1. If D ≠ 0 there is exactly one solution; if D = 0 the lines are parallel (no solution) or the same line (infinite).
