    It's d. (16,21).

    Step-by-step explanation:

    2x - y = 11 ... (1)

    3x - 2y = 6 ... (2)

    Multiply the first equation by - 2:

    -4x + 2y = - 22 ... (3)

    Adding (2) + (3):

    -x = - 16

    x = 16.

    Substitute for x in equation (1):

    2 (16) - y = 11

    -y = 11-32 = - 21

    y = 21.

    d

    Step-by-step explanation:

    Given the 2 equations

    2x - y = 11 → (1)

    3x - 2y = 6 → (2)

    Multiply (1) by - 2 and adding will eliminate y

    - 4x + 2y = - 22 → (3)

    Add (2) and (3) term by term

    (3x - 4x) + ( - 2y + 2y) = (6 - 22)

    - x = - 16 (multiply both sides by - 1)

    x = 16

    Substitute x = 16 into (1) or (2) for corresponding value of y

    (1) : 32 - y = 11 (subtract 32 from both sides)

    - y = - 21 (multiply both sides by - 1)

    y = 21

    Solution is (16, 21) → d
