Solution for 3(x-1)*y-1;3x*2+y system of equations: 


  • /| 3*y*(x-1)-1 = 0| 2*3*x+y = 0
  • We try to solve the equation: 3*y*(x-1)-1 = 0
  • 3*y*(x-1)-1 = 0
  • 3*x*y-3*y-1 = 0
  • -3*y-1 = 0 // + 1
  • -3*y = 1 // : -3
  • y = 1/(-3)
  • y = -1/3
  • We insert the solution into one of the initial equations of our system of equations
  • We get a system of equations:
  • /| 2*3*x-1/3 = 0| y = -1/3
  • 6*x-1/3 = 0 // + 1/3
