Solution for 2x+4y=2;4x+8y=0 system of equations: 


  • /| 2*x+4*y-2 = 0| 4*x+8*y = 0
  • We try to solve the equation: 2*x+4*y-2 = 0
  • 2*x+4*y-2 = 0 // - 2*x-2
  • 4*y = -(2*x-2) // : 4
  • y = (-(2*x-2))/4
  • y = (2-(2*x))/4
  • We insert the solution into one of the initial equations of our system of equations
  • We get a system of equations:
  • /| 8*((2-(2*x))/4)+4*x = 0| y = (2-(2*x))/4
  • (8*(2-2*x))/4+4*x = 0
  • 4 = 0
  • 4 = 0
  • x belongs to the empty set
  • The system of equations does not have any solution
