Solve the quadratic equations and determine the relation between x and y:
Equation 1: 21x² - 82x + 80 = 0
Equation 2: 23y² - 132y + 85 = 0
Equation 1: x² - 200x + 9600 = 0
Equation 2: y² - 190y + 9025 = 0
Equation 1: x² - 180x + 8100 = 0
Equation 2: y² - 170y + 7225 = 0
I. (y – 5)2 – 9 = 0
II. x2 – 3x + 2 = 0
I. 2y2 - 15y + 18 = 0
II. 2x2 + 9x - 18 = 0
