Multiple choice

In each of these questions, two equations are given. You have to solve these equations and find out the values of X and Y and give answers. I. (3x^2 + 2x - 21 = 0) II. (3y^2 - 8y - 16 = 0)

  1. If X < Y

  2. If X > Y

  3. If X ≤ Y

  4. If X ≥ Y

  5. If X=Y or no relation can be established.

Explanation

Equation I: 3x² + 2x - 21 = (3x-7)(x+3) = 0, so x = -3 or 7/3. Equation II: 3y² - 8y - 16 = (3y+4)(y-4) = 0, so y = -4/3 or 4. Comparing values: when x=-3, xy for y=-4/3. Since the relationship varies, no definite relation exists.
