-42 if i am correct because you always do the parentheses first then multiply -6.

Here are the steps to figuring it out :)

1. First, you have to plug in the values. So if a = -6, then you have to plug in -6 in the place of a in the problem.
-6 (14 - 7) <---- This is what the equation would look like after plugging in      the values.
2. Now we always have to solve whatever is in the parentheses next.
14 - 7 = 7
3. After that, multiply -6 by 7
-6 × 7 = -42
