Here is an augmented matrix for a system of equations (three equations and three variables). Let the variables used be x, y, and z: i 2 4 6 L 1 5 B 0 1 4 Note: that this matrix is already in row echelon form. Your goal is to use this row echelon form to revert back to the equations that this represents, and then to ultimately solve the system of equations by finding x, y and z. Input your answer as a coordinate point: (x,y,z) with no spaces
