Subtract 12(z+4)−3(14z+1) . Use fractions in final form. correct answer please

To solve this problem, we will distribute and combine like terms.

First, distribute the first term:
12(z + 4) - 3(14z + 1) = 12z + 48 - 42z - 3

Now, combine like terms:
12z - 42z + 48 - 3 = (12z - 42z) + (48 - 3) = -30z + 45

Therefore, the simplified expression is -30z + 45.
