Example Question #2213 : Algebra 1

Solve for :

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.

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

Solve the following:

Explanation:

Don't forget to change the direction of the inequality sign when dividing by a negative number!

Example Question #2211 : Algebra 1

Give the solution set of the inequality:

The set of all real numbers

Explanation:

Note change in direction of the inequality symbol when the expressions are divided by a negative number.

or, in interval form,

Example Question #2 : How To Find The Solution To An Inequality With Division

Solve for :

Explanation:

First, add and subtract  from both sides of the inequality to get .

Then, divide both sides by and reverse the sign since you are dividing by a negative number.

This gives you .

Example Question #2 : How To Find The Solution To An Inequality With Division

Find the solution set to the following compound inequality statement:

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.
