You have:
2r

6r-21
then move the 6r over to the left and you end up wtih
-4r

-21
Then you divide by -4 and when you do you must flip the inequality so your answer would be
r

21/4
3,1

Step-by-step explanation:
Divide $1,137.50 by 350 to see out how much each book costs. Then divide $1,500 by 350 to see how much the school should add to the price of each agenda book to make the total profit. So the answer should be: (1137.50/350)+(1500/350) = minimum price
The first one is 2x-3y/2
The second one is 1/x+2
The third one is (2x-5y)/(2x+5y)
The fourth one is x^2/z^2
