Solution for 6x-7=39;x-9y=34 system of equations: 


  • /| 6*x-39-7 = 0| x-(9*y)-34 = 0
  • We try to solve the equation: x-(9*y)-34 = 0
  • x-9*y-34 = 0 // - x-34
  • -9*y = -(x-34) // : -9
  • y = (-(x-34))/(-9)
  • y = (34-x)/(-9)
  • We insert the solution into one of the initial equations of our system of equations
  • We get a system of equations:
  • /| 6*x-39-7 = 0| y = (34-x)/(-9)
  • 6*x-46 = 0 // + 46
  • 6*x = 46 // : 6
  • x = 46/6
  • x = 23/3
  • We insert the solution into one of the initial equations of our system of equations
  • For y = (34-x)/(-9): 
  • y = (34-23/3)/(-9)
  • y = 79/3/(-9)
  • y = -79/27
  • We get a system of equations:
  • /| y = -79/27| x = 23/3
