Solution!!

y/4 - y/3 = y/5 + 2/7

Taking the LCM

(3y - 4y)/12 = (7y + 10)/35

Simplifying the numerator

(-y)/12 = (7y + 10)/35

Cross multiplication

35(-y) = 12(7y + 10)

-35y = 84y + 120

Taking the variable to the left-hand side

-35y - 84y = 120

-119y = 120

Solving for y

y = 120/(-119)

Hence, the value of y is -120/119.
