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

a) subtract 3 from each entry of row 2

b) multiply row 1 by - 3 and add the result to row 2

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