3y-5%3C5y%2B7 Start with the given inequality.


3y%3C5y%2B7%2B5 Add 5 to both sides.


3y-5y%3C7%2B5 Subtract 5y from both sides.


-2y%3C7%2B5 Combine like terms on the left side.


-2y%3C12 Combine like terms on the right side.


y%3E%2812%29%2F%28-2%29 Divide both sides by -2 to isolate y. note: Remember, the inequality sign flips when we divide both sides by a negative number.


y%3E-6 Reduce.
