Question

What is a matrix for a system of equations that does not have a unique solution?

Answer 1

A system of linear equations can have no solution, a unique solution or infinitely many solutions. A system has no solution if the equations are inconsistent, they are contradictory. for example 2x+3y=10, 2x+3y=12 has no solution. is the rref form of the matrix for this system.

This is in my opinion. Im not sure if it is correct or not but Good luck!
