Question

Which of these is a simplified form of the equation 9y + 6 = 9 + 2y + 2y

9y = 7

5y = 3

13y = 15

4y = 15

Answer 1

5y = 3

Explanation:

9y + 6 = 9 + 2y + 2y

9y + 6 = 9 + (2y + 2y)

9y + 6 = 9 + 4y subtract 6 from both sides

9y = 3 + 4y subtract 4y from both sides

5y = 3

Answer 2

9y + 6 = 9 + 2y + 2y

9y + 6 = 9 + (2y + 2y)

9y + 6 = 9 + 4y subtract 6 from both sides

9y = 3 + 4y subtract 4y from both sides

5y = 3
