Solution for 20x-20y=-100;-20x+20y=100 system of equations: 


  • /| 20*x-(20*y)+100 = 0| 20*y-20*x-100 = 0
  • We try to solve the equation: 20*x-(20*y)+100 = 0
  • 20*x-20*y+100 = 0 // - 20*x+100
  • -20*y = -(20*x+100) // : -20
  • y = (-(20*x+100))/(-20)
  • y = (20*x+100)/20
  • We insert the solution into one of the initial equations of our system of equations
  • We get a system of equations:
  • /| 20*((20*x+100)/20)-20*x-100 = 0| y = (20*x+100)/20
  • (20*(20*x+100))/20-20*x-100 = 0
  • 100-100 = 0
  • 0 = 0
  • The system of equations has infinitely many solutions
