How man solutions can a system have?

Answer 1

A system of equations can have three types of solutions: one unique solution, infinitely many solutions, or no solution at all. A unique solution occurs when the equations intersect at a single point, while infinitely many solutions arise when the equations represent the same line or plane. No solution occurs when the equations represent parallel lines or planes that do not intersect. The nature of the solutions depends on the relationships between the equations in the system.
