Question

I. 7x + 8y = 36

II. 3x + 4y = 14

Q: I. 7x + 8y = 36 II. 3x + 4y = 14

7x + 8y = 36 .......................(i) 3x + 4y = 14 .......................(ii) Multiplying equation (ii) by 2 We get 6x + 8y = 28.......................(iii) By solving (i) and (iii) => x = 8 => y = -2.5 Hence, x > y.

A if x > y

B if x ≥ y

C if x < y

D if x ≤ y

E if x = y or the relationship cannot be established.
