Look in explanation

Step-by-step explanation:

So, lets break this down.

the given values are -14 for x, and 3 for y.

all you need to do is substitute x and y with the given values.

So, the equation becomes 12(-14)-3(3).

Now, let's do the math.

12*-14 is -168.

-3*3 is -9.

So the equation ends up as -168-9.

-168-9 is -177.

Hence, the answer is -177.
