The first step in simplifying this expression is to identify which, if any, terms can be combined. Remember, only like terms — constant terms or terms with the same variable — can be combined.
5/8m+ 9 - 3/8m - 15
In this case, we have two m-terms and two constants. To simplify the expression we will rearrange it according to the Commutative Property of Addition and then combine like terms.
