3

Addition Property of Equality

States that two sides of an equation stay equal when the same amount is added to both sides of the equation.

4

Multiple Choice

Which of the following shows the addition property of equality of the equation below?

 10+15=2510+15=25  

1

 10+15=25+510+15=25+5  

2

 (10+15)+5=25+5\left(10+15\right)+5=25+5  

3

 (10+15)+5=25\left(10+15\right)+5=25  

4

 10=25+1510=25+15  

5

Subtraction Property of Equality

States that when you subtract the same amount from both sides of an equation the two sides of the equation stay equal.

6

Multiple Choice

Which of the following shows the subtraction property of equality of the equation below?

 19+12=3119+12=31  

1

 19+12=31−619+12=31-6  

2

 19=31−1219=31-12  

3

 (19+12)−6=31\left(19+12\right)-6=31  

4

 (19+12)−6=31−6\left(19+12\right)-6=31-6  

7

Multiplication Property of Equality

States that when you multiply both sides of an equation by the same amount the two sides of the equation stay equal.

8

Multiple Choice

Which of the following shows the multiplication property of equality of the equation below?

 6−3=36-3=3  

1

 6−3=3×76-3=3\times7  

2

 (6−3)×7=3×7\left(6-3\right)\times7=3\times7  

3

 6=(3−3)×76=\left(3-3\right)\times7  

4

 (6−3)×7=3\left(6-3\right)\times7=3  

9

Division Property of Equality

States that when you divide both sides of an equation by the same non-zero amount the two sides of the equation stay equal.

10

Multiple Choice

Which of the following shows the division property of equality of the equation below?

 40−10=3040-10=30  

1

 40−10 =30÷540-10\ =30\div5  

2

 (40−10)÷5=30\left(40-10\right)\div5=30  

3

 40=(30−10)÷540=\left(30-10\right)\div5  

4

 (40−10)÷5=30÷5\left(40-10\right)\div5=30\div5  

11

Multiple Choice

Choose which property of equality was used.

 5m+4=195m+4=19  
 5m+4−3=19−35m+4-3=19-3
