-2r-7%3E=-9-r Start with the given inequality.


-2r%3E=-9-r%2B7 Add 7 to both sides.


-2r%2Br%3E=-9%2B7 Add r to both sides.


-r%3E=-9%2B7 Combine like terms on the left side.


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


r%3C=%28-2%29%2F%28-1%29 Divide both sides by -1 to isolate r. note: Remember, the inequality sign flips when we divide both sides by a negative number.


r%3C=2 Reduce.
