Inequalities
 

Inequalities are manipulated algebraically the same way as equations with one exception:
 

Multiplying or dividing both sides of an inequality by a negative number reverses the inequality. That is, if x > y and c < 0, then cx < cy.

 

Example:

For which values of x is 4x + 3 > 6x – 8?

As with equations, our goal is to isolate x on one side:

Subtracting 6x from both sides yields

––2x + 3 > ––8

Subtracting 3 from both sides yields

––2x > ––11

Dividing both sides by –2 and reversing the inequality yields

x < 11/2
