x2 - 16 = 0 y2 - 9y + 20 = 0

Direction: In each of the following question, there are two equations. you have to solve both equations and give answer.

1. if x > y
2. if x ≥ y
3. if x < y
4. if x ≤ y
5. If x = y or relation cannot be established

x² - 16 = 0
⇒ x² = 16 ⇒ x = √16 = ± 4
and y² - 9y + 20 = 0
y² - 4y - 5y + 20 = 0
⇒ y(y - 4) - 5(y - 4) = 0
⇒ y = 5, 4
⇒ y ≥ x or x ≤ y
