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.
