hi Tinu ,
Given :
x/3 + y/4 = 4
multiply whole equation by 12
4x + 3y = 48 ...(1)
5x/6 - y/8 = 4
multiply whole equation by 24
20x - 3y = 96 ...(2)
adding 1 and 2
4x + 3y - 48 = 0 ...(1)
20x - 3y - 96 = 0 ...(2)
we get
24x = 144
x = 6
so
using 4x + 3y = 48
4*6 + 3y = 48
3y = 48 - 24
y = 24/3
y = 8
Hope it helped
Let me know if any doubts
Cheers !!!

hope u liked my solution
pls mark it as brainliest
you multiply 12 or 24 why
to bring the equation terms into multiples and not fractions
multiply with the LCM : x/3 + y/4 = 4 LCM of 3 and 4 is 12
similarly 5x/6 - y/8 = 4 LCM of 6 and 8 is 24
