Solution for x=4y-1;3x-12y=-3 system of equations: 


  • /| x-(4*y)+1 = 0| 3*x-(12*y)+3 = 0
  • We try to solve the equation: x-(4*y)+1 = 0
  • x-4*y+1 = 0 // - x+1
  • -4*y = -(x+1) // : -4
  • y = (-(x+1))/(-4)
  • y = (x+1)/4
  • We insert the solution into one of the initial equations of our system of equations
  • We get a system of equations:
  • /| 3*x-(12*((x+1)/4))+3 = 0| y = (x+1)/4
  • (-1*12*(x+1))/4+3*x+3 = 0
  • 3-3 = 0
  • 0 = 0
  • The system of equations has infinitely many solutions
