Question

How can i solve this using distributive property ?

Answer 1

8a + 4 =28

a = 3

Explanation:

1. 2/3 (12a + 6) = 28

2/3 x 12a = 8a

2/3 x 6 = 4

2. add the equation together:

8a + 4 = 28

3. solve if needed

8a + 4 = 28

- 4 - 4

============

8a = 24

4. get a alone to figure out what a equals:

8a 24

---- = -------

8 8

a = 3
