Task 9: Summary of the Math: Properties of Equality
Read and Discuss
 Addition property of equality : If a=b, then a+c=b+c.
 Multiplication property of equality : If a=b, then ac=bc.

These two properties of equality are very useful. For any equation that is true, you can
 Add the same value to both sides or subtract the same value from both sides and the equation will still be true.
 Multiply or divide both sides by the same value and the equation will still be true.
Can you:
 Provide examples of equations that can be solved using the addition property of equality, and explain the steps for using the property to solve each equation?
 Provide examples of equations that can be solved using the multiplication property of equality, and explain the steps for using the property to solve each equation
