Work Step by Step

Original expression: $4+(105x+5)$ Combine like terms. 4 and 5 are the only terms we can combine because there are no other variables in the expression. We can add these because of the associative property of addition. $5+4=9$ The expression should now look like this: $105x+9$ It is impossible to simplify this further because all like terms have already been combined. So your final, simplified answer is $105x+9$.
