Solving Equations by Multiplying or Dividing Section 2-12 Solving Equations by Multiplying or Dividing

Multiplication Property of Equality Multiply both sides of an equation by the same number, and the statement will still be true.

Example 1 Solve the equation h/2 = 13. Check your answer.

Division Property of Equality Divide both sides of an equation by the same nonzero number, and the statement will still be true.

Example 2 Solve the equation 51 = 17x. Check your answer.

Example 3 If you count your heartbeats for 10 seconds and multiply that number by 6, you can find your heart rate beats per minute. Trevor’s heart rate is 78 beats per minute. How many times does his heart beat in 10 seconds?
