Example Question #1 : How To Find The Solution To An Inequality With Division

Solve for :

Possible Answers:

None of the other answers

Correct answer:

Explanation:

To solve for , separate the integers and 's by adding 1 and subtracting from both sides to get . Then, divide both sides by 2 to get . Since you didn't divide by a negative number, the sign does not need to be reversed.

Possible Answers:

Correct answer:

Explanation:

Solve each of these two inequalities separately:

 

, or, in interval form, 

 

, or, in interval form, 

 

The two inequalities are connected with an "and", so we take the intersection of the two intervals.
