Grace [21]

Answer:

-5+5r-2 -->

--> 5r-7 <--

Explanation --

Distribute from the parentheses, of course excluding the -2 because it isn't involved, and you'll get --> -5 + 5r -2

Simplify by putting the like terms together (subtract) -->

5r -7 (you get -7 by doing -5-2, and you leave 5r by itself since it doesn't have anything more to simplify with or has any other like term)

So, the final, simplified answer -->

5r-7

Hope this helps!! Have a nice day! :)
