# The reduced row echelon form of the augmented matrix of a system of linear equations is given. Tell whether the system has one solution, no solution,

Forms of linear equations
The reduced row echelon form of the augmented matrix of a system of linear equations is given. Tell whether the system has one solution, no solution, or infinitely many solutions. Write the solutions or, if there is no solution, say the system is inconsistent. [1200−4 0010−3 00012 00000]

There are no impossible equations, such as $$(0=1)$$, the system is consistent,
