# Pre-Algebra

What is the answer to this one?
4/7y - 8 = 2/7y + 10

4/7y - 8 = 2/7y + 10
(4/7y - 8) - 2/7y = (2/7y + 10)- 2/7y

2/7y - 8 = 10
2/7y - 8 + 8 = 10 - 8
2/7y = 2
(2/7 y)/ 2/7 = 2/1 / 2/7
y = 2/14 or 1/7

• Pre-Algebra -

7y - 8 = 2/7y + 10

4/7y - 8 = 2/7y + 10
(4/7y - 8) - 2/7y = (2/7y + 10)- 2/7y

2/7y - 8 = 10
2/7y - 8 + 8 = 10 - 8 ((((((error here should be +8 on the right))))

• Pre-Algebra -

does y = 63

• Pre-Algebra -

2/7y = 18
(2/7y) / 2/7 = 18 / (2/7)
y = 63

• Pre-Algebra -

correct

Thank you again! Really appreciate it.
