Explanation:

-7y > 161

7y < 161

7÷7=1

161÷7=23

y=23

7y > -161

7÷7=1

-161÷7=-23

y=-23

Sample response: Both inequalities use the division property to isolate the variable, y. When you divide by a negative number, like –7, you must reverse the direction of the inequality sign. When you divide by a positive number, like 7, the inequality sign stays the same. The solution to the first inequality is y > -23, and the solution to the second inequality is y <>
