The tone of her voice seemed to ______ that she knew

I. 24x² - 58x + 23 = 0

II. 20y² + 24y – 65 = 0

I. 4x² + 25x + 36 =0

II. 2y² + 5y + 3 = 0

I. 7p + 8q = 80

II. 9p – 5q = 57

I. 2x² - 7x + 3 = 0

II. 8y² - 14y + 5 = 0

In the question, two equations I and II are given. You have to solve both the equations to establish the correct relation between x and y.

I. 20y² - 13y + 2 = 0

II. 6x² - 25x + 14 = 0

I. 35 y² + 58 y + 24 = 0

II. 21 x² + 37 x + 12 = 0

I. 2x² – 5x - 12 = 0

II. y² – 11y + 30 = 0

I. 5x² - 24 x + 28 = 0    

II. 4y² - 8 y  - 12= 0    

Solve the quadratic equations and determine the relation between x and y:

Equation 1: 19x² - 88x + 100 = 0
