$14+8a-(7b-13-2a)=\text{?}$

First, we address the exercise within the parentheses:

Remember that:

When we multiply a positive number by a negative number, the result will be negative.

When we multiply a negative number by a negative number, the result will be positive.

Now we obtain:

$14+8a-7b+13+2a=$

We join the coefficients to:

$8a+2a=10a$

We join the numbers without coefficients:

$14+13=27$

We obtain:

$27+10a-7b$
