  • Math 115 15 & 16 -

    From you notation, it is not clear whether the denominator is just the first of the two terms or both of them. I will first assume it is just the first number.

    [10-15/(3)] (6) -12 = (-5/3)(6) - 12 = -10 - 12 = -22

    Now if it is both numbers.

    [10-15/(3)(6)] -12 = -5/18 - 12 = - 5/18 -216/18 = -221/18

    Decide on your denominator and go through the same processes for the second problem.

    I hope this helps. Thanks for asking.
