Multiple choice

Find x and y from 1/x - y + 5/3x - 2y = 2 and 15/3x - 2y = 2 - 2/x - y = 1.

  1. x = 3, y = 2

  2. x = 2, y = 3

  3. x = 4, y = 5

  4. x = 5, y = 4

  5. x = 1, y = 4

A Correct answer
Explanation

Take 1/x - y = a and 1/3x - 2y = b a + 5b = 2 ……(1) 15b – 2a = 1 ……(2) (1) × 2 + (2) ⇒ b = So, a = 1. x – y = = 1 ……..(3) and 3x – 2y = = 5 ……(4) So, x = 3; y = 2 Option 1 is correct.
