(3x – 2)/y = (3x + 6)/(y + 16)

(x + 2)/(y + 4) = (x + 5)/(y + 10)

X > Y

X < Y

X ≥ Y

X = Y or relation cannot be established

Explanation:

Answer & Explanation
X < Y
Explanation:
(3x – 2)/y = (3x + 6)/(y + 16)
y + 16(3x – 2) = y (3x + 16)
48x – 8y = 32 —(a)
(x + 2)/(y + 4) = (x + 5)/(y + 10)
(x + 2)(y + 10) = (x + 5)(y + 4)
2x = y —(b)
From (a) and (b) x = 1, y = 2
