In the following question two equations numbered I and II are given. You have to solve both the equations and Give answer
I. 5x + 2y = 31
II. 3x + 7y = 36
A) x > y
B) x \( \Large \geq \) y
C) x < y
D) x \( \Large \leq \) y
Correct answer:
A) x > y
Description for Correct answer:
By equation I \( \Large \times \) 3 - equation II \( \Large \times \) 5, we have,
15x + 6y - 15x - 35y = 93 - 180
=> - 29y = - 87 => y = \( \Large \frac{87}{29} \) = 3
From equation I,
5x + 2 \( \Large \times \) 3 = 31
=> 5x = 31 - 6 = 25 => x = 5
Clearly, x > y
