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.
0.5w+1.7w - 0.5
In this case, we have two w-terms and one constant.
Only the w-terms can be combined, so to simplify the expression we will rearrange it according to the Distributive Property to combine the like terms.
