    Step-by-step explanation:

    Inverse proportion.

    z = k/w

    z = 3, w = 4

    Solve for k constant.

    3 = k/4

    (4) 3 = (4) k/4

    12=k

    The value of k constant is 12.

    z = k/w

    Put w as 2 and k as 12 and solve for z.

    z = 12/2

    z = 6

    The value of z when w equals 2 is 6.
