I. 2x² – 5x – 63 = 0

II. 2y² – 7y – 72 = 0

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

Equation 1: 27x² - 114x + 99 = 0

Equation 2: 18y² - 70y + 68 = 0

I. x² – 13x + 40 = 0

II. 2y² – 15y + 13 = 0 

I. 144x² - 163x - 65 = 0

II. 91y² - 128y -48 = 0

Equation 1: x² - 180x + 8100 = 0

Equation 2: y² - 170y + 7225 = 0

I. 63x² + 146x + 80 = 0

II. 42y² + 109y + 70 = 0

I.√(3x-17)+ x=15

II.  y+  135/y=24 

I. 2x² – 5x – 12 = 0

II. 2y² + 13y + 20 = 0

How many values of x and y satisfy the equation 2x + 4y = 8 & 3x + 6y = 10.
