Initial Matrix

Taking matrix to echelon form:

multiplying row by 0.3333}}}
adding times row to row
adding times row to row
multiplying row by
adding times row to row
multiplying row by

Taking matrix to reduced echelon form:
adding 1.3333 times row 2 to row 1
adding 0.7143 times row 3 to row 1
adding 0.2857 times row 3 to row 2
Reduced echelon form:
