6(-4x - 7) - 4(x - 6)       Distribute 6 into (-4x - 7) and -4 into (x - 6)

(6)(-4x) + (6)(-7) + (-4)x + (-4)(-6)  (two negative signs cancel each other out and become positive)

-24x - 42 - 4x + 24    Combine like terms(terms that have the same variable and power/exponent)

-24x - 4x - 42 + 24    (I rearranged the terms to be next to their like term)

-28x - 18      Your answer is D
