No.
-1 > 2r - 5 > -9
-1 + 5 > 2r - 5 + 5 > -9 + 5
4 > 2r > -4
2 > r > -2
-2 < r < 2
or r (member of range) (-2,2)

-1 > 2r-5 > -9
Add 5 to all three figures :
4 > 2r > -4
Divide by 2 :
2 > r > -2
That's your solution

There is a solution. Split the problem in two
2r-5 < -1
2r-5 > -9
2r < 4 --> r < 2
2r > -4 -->r > -2
-2 < r < 2
