Solution for x+y3;2x-y3 system of equations: 


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