OBJECTIVES 2.2 Solving Equations: The Multiplication Principle Slide 3Copyright 2011, 2007, 2003, 1999 Pearson Education, Inc. aSolve equations using the multiplication principle.

4
For any real numbers a, b, and c with c 0, a = b is equivalent to a ∙ c = b ∙ c. 2.2 Solving Equations: The Multiplication Principle The Multiplication Principle for Equations Slide 4Copyright 2011, 2007, 2003, 1999 Pearson Education, Inc.

5
EXAMPLE Solution6x = 96 The solution is 16. Divide by the same number on both sides of = sign. In this case divide by 6. 2.2 Solving Equations: The Multiplication Principle a Solve equations using the multiplication principle. ASolve 6x = 96. Slide 5Copyright 2011, 2007, 2003, 1999 Pearson Education, Inc. 6 Check: 6x = 96 6(16) 96 96 TRUE x = 16

6
EXAMPLE Solution 7x = 84 Dividing both sides by 7. 2.2 Solving Equations: The Multiplication Principle a Solve equations using the multiplication principle. BSolve: –7x = 84 Slide 6Copyright 2011, 2007, 2003, 1999 Pearson Education, Inc. Check: 7x = 84 7( 12)| 84 84 = 84 The solution is 12. Identity Property of 1.
