Solution for 2x=4y+3;2x=4y-2 system of equations:


  • /| 2*x-(4*y)-3 = 0| 2*x-(4*y)+2 = 0
  • We try to solve the equation: 2*x-(4*y)-3 = 0
  • 2*x-4*y-3 = 0 // - 2*x-3
  • -4*y = -(2*x-3) // : -4
  • y = (-(2*x-3))/(-4)
  • y = (3-(2*x))/(-4)
  • We insert the solution into one of the initial equations of our system of equations
  • We get a system of equations:
  • /| 2*x-(4*((3-(2*x))/(-4)))+2 = 0| y = (3-(2*x))/(-4)
  • (-1*4*(3-2*x))/(-4)+2*x+2 = 0
  • 2+3 = 0
  • 5 = 0
  • 5 = 0
  • x belongs to the empty set
  • The system of equations does not have any solution
