Solution for 9x-7y=0;-18x+14y=1 system of equations: 


  • /| 9*x-(7*y) = 0| 14*y-18*x-1 = 0
  • We try to solve the equation: 9*x-(7*y) = 0
  • 9*x-7*y = 0 // - 9*x
  • -7*y = -(9*x) // : -7
  • y = (-(9*x))/(-7)
  • y = (-9*x)/(-7)
  • We insert the solution into one of the initial equations of our system of equations
  • We get a system of equations:
  • /| 14*((-9*x)/(-7))-18*x-1 = 0| y = (-9*x)/(-7)
  • -1 = 0
  • x belongs to the empty set
  • The system of equations does not have any solution
