1. 2-10 Solving Inequalities by Multiplying or Dividing
What You’ll Learn
To solve inequalities by dividing
To solve inequalities by multiplying

2. Example 1: Solving inequalities by Dividing
Solve – 3y < -27
-3y < -27
-3y/3 > -27/-3
y > 9
Divide each side by -3
Reverse the direction of the symbol
Because dividing by a negative
simplify

3. Solve and graph each inequality
- 8m > -24
7n > - 21

4. Solve Inequalities by Multiplying
Solve y/-8 > 2
y / -8 > 2
y / -8 * - 8 < 2 * - 8
y < - 16
Multiply each side by – 8
Reverse sign
Because multiplying by a negative
Simplify

5. Solve and Graph Inequalities
k / -5 < - 4
p / - 7 > 6
m / 9 < - 6
