    The matrix representing the system is (A|B)=()⟶(−−− −)⟶(). where we see that.
    We know from working with systems of equations in two variables that a dependent system of equations has an infinite number of solutions. In order to solve systems of equations in three variables, known as three-by-three systems, the primary goal is to eliminate one variable at a time to achieve back-substitution. They can only be solved by a strong insight and practice only. Doing so uses similar techniques as those used to solve systems of two equations in two variables.

    Just as with systems of equations in two variables, we may come across an inconsistent system of equations in three variables, which means that it does not have a solution that satisfies all three equations.
