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

if we substract that from
25b+20c=690
5b=90
b=18 she worked as a blacksmith for 18 hours
