  3. x = 3, y = 12

    Step 2: Enter the values for your matrix, and press the "Solve" button.



    Divide row1 by 4
    1 -1/2 -3
    3 -1 -3

    Add (-3 * row1) to row2
    1 -1/2 -3
    0 1/2 6

    Divide row2 by 1/2
    1 -1/2 -3
    0 1 12

    Add (1/2 * row2) to row1
    1 0 3
    0 1 12
