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
