Solution for x=8y+2;x=6y+4 system of equations: 


  • /| x-(8*y)-2 = 0| x-(6*y)-4 = 0
  • We try to solve the equation: x-(8*y)-2 = 0
  • x-8*y-2 = 0 // - x-2
  • -8*y = -(x-2) // : -8
  • y = (-(x-2))/(-8)
  • y = (2-x)/(-8)
  • We insert the solution into one of the initial equations of our system of equations
  • We get a system of equations:
  • /| x-(6*((2-x)/(-8)))-4 = 0| y = (2-x)/(-8)
  • (-1*6*(2-x))/(-8)+x-4 = 0
  • 1/4*x-4+3/2 = 0
  • 1/4*x-5/2 = 0
  • 1/4*x-5/2 = 0 // + 5/2
  • 1/4*x = 5/2 // : 1/4
  • x = 5/2/1/4
  • x = 10
  • We insert the solution into one of the initial equations of our system of equations
  • For y = (2-x)/(-8): 
  • y = (2-10)/(-8)
  • y = -8/(-8)
  • y = 1
  • We get a system of equations:
  • /| y = 1| x = 10
