Step 1. The expression that we have is:

And we need to solve the operations to find the answer.
Step 2. We need to make the multiplications first:
(-6)(-2)=12
and
(+8)(-4)=-32
here we have applied the law of signs:

The solution to the multiplications is shown here:
The expression now is:

Step 3. Now we solve the expression considering that
(+)(-) is -

The result of the subtraction is:

Answer:
