Example 2 Solve this system by using matrices. Multiply 2 times row 1 and –5 times row 2; then add:  This matrix now represents the system  Therefore,   y  = 1  Now, substitute 1 for  y  in the other equation and solve for  x Check the solution. The solution is  x  = 3,  y  = 1.  Matrices are a more time-consuming method of solving systems of linear equations than either the
