Answer:

(3y -2)/7 - (5y - 8)/4 = 1/14

=> {(12y - 8) - (35y - 56)} / 28 = 1/14

=> 12y - 8 - 35y + 56 = 28/14

=> 48 - 23y = 2

=> 23y = 48 - 2

=> 23y = 46

=> y = 46/23

=> y = 2 ans.

Answer:

 \frac{3y - 2}{7}  -  \frac{5y - 8}{4}  =  \frac{1}{14}  \\  \frac{12y -8 - 35y + 56}{28}  =  \frac{1}{14}  \\  \frac{48 -13y }{28}  =  \frac{1}{14}  \\ 48 - 23y = 2 \\ 23y = 46 \\ y = 2

y = 2 is the right answer.
