    EQUATION: Z = kxy

    3 = k (3)(15)

    3 = k (45)

    3/45 = k 45/45

    1/15 = k

    z = (1/15)(6)(9)

    z = (2/5)(9)

    z = 18/5

    ANSWER: z = 18/5

    EQUATION: Z = kxy

    3 = k (3)(15)

    3 = k 45

    3 / 45 = k 45 / 45

    1 / 15 = k

    z = (1 / 15) (6) (9)

    z = 18 / 5

    ANSWER: z = 18 / 5

    z = (1/15)(54)

    z = 18/5

    ANSWER: z = 18/5 or 3.6

    Example 1 – If y varies jointly as x and z, and y = 12 when x = 9 and z = 3, find z when y = 6 and x =15. Step 1: Write the correct equation. Joint variation problems are solved using the equation y = kxz. ... Step 3: Rewrite the equation from step 1 substituting in the value of k found in step 2.
