    42

    Step-by-step explanation:

    Open the bracket first

    (X3-15) - (y+6)

    X3-15-y-6

    Collect like terms

    X3-y-15-6

    X3-y-21

    And x is said to be 4, y to be 1

    So let's substitute

    (4) ^3 - (1) - 21

    64-1-21

    64-22

    42

    Therefore the final answer is 42
