Step-by-step explanation:

Given  

1/x + 1/y = 12 ;3/x-2/y = 1 solve by simultaneous equation

  • We need to solve by simultaneous equation.
  • So given equations are
  • 1/x + 1/y = 12 multiply by 3
  • 3/x – 2/y = 1
  • So we get
  • 3/x + 3/y = 36
  • 3/x – 2/y = 1
  • Subtracting we get
  • 3/y + 2/y = 35
  • 5/y = 35
  • Or y = 1/7
  • Substituting the value of y we get
  • 3/x + 3/1/7 = 36
  • 3/x + 21 = 36
  • 3/x = 36 – 21
  • 3/x = 15
  • Or x = 1/5
