Solution for x-y=5;3x+2y=0 system of equations: 


  • /| x-y-5 = 0| 3*x+2*y = 0
  • We try to solve the equation: x-y-5 = 0
  • x-y-5 = 0 // - x-5
  • -y = -(x-5) // * -1
  • y = x-5
  • We insert the solution into one of the initial equations of our system of equations
  • We get a system of equations:
  • /| 2*(x-5)+3*x = 0| y = x-5
  • 2*(x-5)+3*x = 0
  • 5*x-10 = 0
  • 5*x-10 = 0 // + 10
  • 5*x = 10 // : 5
  • x = 10/5
  • x = 2
  • We insert the solution into one of the initial equations of our system of equations
  • For y = x-5: 
  • y = 2-5
  • y = -3
  • We get a system of equations:
  • /| y = -3| x = 2
