Web4 Answers. There is the all zero solution (i.e. the trivial solution). A system is defined as inconsistent if its row-reduced echelon form contains a row of form [ 0 0 0... 0 k] where k ≠ 0 and is a separator within augmented matrix. Since your system equals 0 →, it is impossible to have k ≠ 0, rendering the system consistent.

In mathematics and particularly in algebra, a system of equations (either linear or nonlinear) is called consistent if there is at least one set of values for the unknowns that satisfies each equation in the system—that is, when substituted into each of the equations, they make each equation hold true as an identity. In contrast, a linear or non linear equation system is called inconsistent if there is no set of values for the unknowns that satisfies all of the equations.
