Answer:

There are many expressions equivalent to this one, but an example would be 2.5x - 5y - 2.5

Step-by-step explanation:

In this version of the expression, you don't need the parenthesis. If a term is along in parenthesis and all of the operations are addition and subtraction, you can eliminate it.

Also, if you add a negative number, it is the same as subtracting.
