The matrix method is being used to solve the system of equations x + 2y = 4 and 3x - y = 6.


If the goal of the first matrix operation is to get a zero in row 2, column 1, then one could

Asubtract 3 from each entry of row 2

Bmultiply row 1 by -3 and add the result to row 2

c)divide row 2 by -3 and add to row 1
