A system of linear equations is a set of two or more equations with the same variables. The solution is the point(s) where all equations are satisfied simultaneously.
ସୂତ୍ର
General: Ax = b where A is coefficient matrix, x is variable vector, b is constant vector
- A
- coefficient matrix (m × n)
- x
- variable vector (n × 1)
- b
- constant vector (m × 1)

How many solutions can a linear system have?
Zero (inconsistent), exactly one (unique), or infinitely many (infinitely many). It depends on rank and consistency.
When is a system inconsistent?
When the equations contradict (e.g., 0 = 1 after reduction). Geometrically: lines/planes don't all meet at a point.
Can I use elimination or substitution for large systems?
Yes, but matrix methods (Gaussian elimination, LU decomposition) are more efficient for computers.
