Question

9x – 17.45 = 67.55 + 4x, (y – 6)(y – 5) = (y – 4)(y – 3)

  • A) X > Y
  • B) X < Y
  • C) X ≥ Y
  • D) X ≤ Y
  • E) X = Y or relation cannot be established
Solution

A. X > Y
Explanation:
9x – 17.45 = 67.55 + 4x
9x – 4x = 67.55 + 17.45
5x = 85 => x= 17
(y – 6)(y – 5) = (y – 4)(y – 3)
4y = 18; y = 4.5

A. X > Y
Explanation:
9x – 17.45 = 67.55 + 4x
9x – 4x = 67.55 + 17.45
5x = 85 => x= 17
(y – 6)(y – 5) = (y – 4)(y – 3)
4y = 18; y = 4.5
