Question

Explain how solving -7y > 161 is different from solving 7y > -161.

Answer 1

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 <>

Answer 2

y>-23 for 7y >-161

y<-23 for -7y>161

Explanation:

For 7y > -161

Divide both sides by 7 and the greater than sign stays the same. The results are y > -23.

For -7y > 161:

Divide both sides by -7.

Change the greater than symbol: > to a less than symbol: < and the results are:

y < -23
