When there is a number next to brackets it means multiply the outside number by what is inside the brackets, so...

If you didn't understand what colbtech said, multiply 'n' by 2 which is in front of the brackets, then '-4' by 2. For example,
10(x-2)
{10}\times{x} + {10}\times{-2}
10x - 20

2(n-4) + 3
Multiply the outside number into the parenthesis.
2n -8 +3
