  • A X = 5[(s − 2) ÷ t] + 3yt
  • B X = 25[(s − 2) ÷ t] − 3ty
  • C X = [1 ÷ (s − 2)3ty]
  • D X = [5(s − 2) 2 ÷ 3ty] x t
Correct Answer: Option B
Explanation:
2 + t/5(x + 3/5y ) = s
t/5(x + 3/5y ) = s − 2
[(t(5x + 3y) ÷ 25)] = s − 2
t(5x + 3y) = 25 (s − 2)
5x + 3y = [(25(s − 2))÷ t]
5x = [(25(s − 2))÷ t] − 3y
Divide both sides by 5
x = [25(s − 2) − 3ty)]÷ 5t
