Given that the augmented matrix in row-reduced form is equivalent to the augmented matrix of a system of linear equations, do the following. (Use x, y, and z as your variables, each representing the columns in turn.) 0 1 0 1 4
0 0 1 −4 5
0 0 0 0 0
0 0 0 0 0

Required:
a. Determine whether the system has a solution.
b. Find the solution or solutions to the system, if they exist.

Could somebody me with this radical simplification?
