Somebody expects you to solve a 2 by 2 system using matrices with echelon reduced form ??
That's like going to the corner store to buy milk in an 18 wheeler tractor-trailer.

Furthermore the system has no solutions, since if you multiply the first by 5, you get
20x - 10y = 45
now subtract the two to get
0 = 18
CONTRADICTION, so no solution.
