-8r%2B8%3C-2%283r-9%29 Start with the given inequality.


-8r%2B8%3C-6r%2B18 Distribute.


-8r%3C-6r%2B18-8 Subtract 8 from both sides.


-8r%2B6r%3C18-8 Add 6r to both sides.


-2r%3C18-8 Combine like terms on the left side.


-2r%3C10 Combine like terms on the right side.


r%3E%2810%29%2F%28-2%29 Divide both sides by -2 to isolate r. note: Remember, the inequality sign flips when we divide both sides by a negative number.


r%3E-5 Reduce.
