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

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)))) 
does y = 63

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

Thank you again! Really appreciate it.
