3.If a system of equations has corresponding matrix whose reduced echelon form has only pivots (leadingentries) to the left of the augment line, but there are fewer pivots than variables, how do we knowthere are infinitely many solutions?

Linear equations when the number of pivots is less than the number of variables will always result…
