Answer

$11+3x$

Work Step by Step

Original expression: $(2+3x)+9$ Combine like terms. 2 and 9 are the only terms we can combine because there are no other like terms to combine in the expression. $2+9=11$ The expression should now look like this: $11+3x$ It is impossible to simplify this further because all like terms have already been combined. So your final, simplified answer is $11+3x$.
