Solution for 9x-8y=15;27x-24y=3 system of equations: 


  • /| 9*x-(8*y)-15 = 0| 27*x-(24*y)-3 = 0
  • We try to solve the equation: 9*x-(8*y)-15 = 0
  • 9*x-8*y-15 = 0 // - 9*x-15
  • -8*y = -(9*x-15) // : -8
  • y = (-(9*x-15))/(-8)
  • y = (15-(9*x))/(-8)
  • We insert the solution into one of the initial equations of our system of equations
  • We get a system of equations:
  • /| 27*x-(24*((15-(9*x))/(-8)))-3 = 0| y = (15-(9*x))/(-8)
  • (-1*24*(15-9*x))/(-8)+27*x-3 = 0
  • 45-3 = 0
  • 42 = 0
  • 42 = 0
  • x belongs to the empty set
  • The system of equations does not have any solution
