**PsyDAG**, Tuesday, February 23, 2010 at 12:23pmDeal with inequalities just like equations, except that you reverse the carats when multiplying or dividing by a negative number.

Is there a typo in the first inequality?

5-(3) < 10(-3)

2 < -30 (That certainly is not true. Think of it in terms of money. Having $2 is not less than owing $30.)

3 < 2x+1 < 9

Subtract 1 from each part.

2 < 2x < 8

Divide each part by 2.

1 < x < 4

Use these principles in the remaining problems.
