In the following question two equations numbered I and II are given. You have to solve both the Equations and ____ Give answer
I. 14x - 25 = 59 - 7x
II. \( \Large \sqrt{y + 222} - \sqrt{36} \) = \( \Large \sqrt{81} \)
Correct Answer: Description for Correct answer:
I. 14x + 7x = 59 + 25
=> 21x = 84
=> x = \( \Large \frac{84}{21} = 4 \)
II. \( \Large \sqrt{y + 222} = \sqrt{36} + \sqrt{81} \)
=> \( \Large \sqrt{y + 222} \) = 6 + 9 = \( \Large \pm \) 15
\( \Large \therefore \) y + 222 = 225
=> y = 225 - 222 = 3
Clearly, x > y
