Crossing Point
Each equation is a line. Find where they cross, and spot when a system has no single solution.
The experiment opens when it comes into view.
Theory and model assumptions
a₁x + b₁y = c₁, a₂x + b₂y = c₂. det = a₁b₂ − a₂b₁. det ≠ 0 gives one solution (Cramer’s rule); det = 0 means parallel or identical lines.
