Three examples of Addition property of equality. Show your solution.

 

Answer:

1. x - 10 = 3

x - 10 + 10 = 3 +10 (Addition property of equality)

x = 13

Checking:

x = 13

x - 10 = 3

13 -10 = 3

3 = 3

2. x - 2 = 5

x - 2 + 2 = 5+ 2 (Addition property of equality)

x = 7

Checking:

x = 7

x - 2 = 5

7 -2 = 5

5 = 5

3. x - 4 = 8

x - 4 + 4 = 8 + 4 Addition property of equality)

x = 12

Checking:

x = 12

x - 4 = 8

12 -4 = 8

8 = 8
