Answer

5x+5

Work Step by Step

Like terms must (1) be raised to the same power and (2) consist of the same variable (i.e. x and y are not like terms). It is also important to note that numbers are all like terms with each other when not multiplied by anything. Thus, combining like terms, we obtain: $$9x-4x+5 \\ 5x+5$$
