Question

Which statement is true about the equation z = z – 3 + 5? (5 points) It has no solution. It has one solution It has two solutions. It has infinitely many solutions.

Answer 1

i dunno

The three types of solution sets:

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.
