    the answer is - 2

    Step-by-step explanation:

    Since x=5 and y=20, plug those values into the correct variables in the equation of 4x-1/2y-12.

    When we do that it brings us to:

    4 (5) - 1/2 (20) - 12

    Then we just simplify:

    20-10-12

    Simplify again:

    10-12

    So 10-12 is - 2, therefore - 2 is the answer
