Hi the answer to your question is

 

((3y - 3.5) / (3y + 6)) 25.5 = (17
/ 25.5) 25.5

((3y - 3.5) / (3y + 6)) 25.5 = 17
(76.5y - 89.25) / (3y + 6) = 17

((76.5y - 89.25) / (3y + 6)) (3y +
6) = 17 * (3y + 6) 76.5y - 89.25 = 51y + 102 76.5y - 51y = 102 + 89.25

25.5y = 191.25

y = 191.25 / 25.5

y = 7.5
