Answer:
-8 < r < 3
Step-by-step explanation:
Because you are trying to solve for r, all we have to do is isolate the variable.
To do this we can divide all 3 terms by -3, because that's what's in front of the r.
24/-3 > -3r/-3 > -9/-3
Dividing or multiplying by a negative number reverses this inequality, so the > signs must be flipped around to <
All that's left to do is simplify the fractions, and ensure that the inequality signs are flipped.
