3/x = 2
2x = 3
x = 3/2 = 1.5
y/4 = 3
y = 4*3 = 12
3 + y = 3 + 12 = 15
x + 4 = 3/2 + 4 = 11/4
(3 + y)/(x + 4) = 15/(11/2)
= 30/11
= 2.72727272....
= 2.73 (approximately)

3/x = 2 or 2x = 3 or x =3/2
y/4 = 3 or y = 12
3 + y/x + 4 = 3 + 12/(3/2) + 4 = 3 + 24/3 + 4
= 3 + 8 + 4 = 15
Therefore, 3 + y/x + 4 = 15

3 / x = 2
Therefore 2x = 3 and x = 3 / 2
y/ 4 = 3
y = 12
3 + 12 / (3 / 2) + 4 = 2 + 8/11 or 30/11
