Solution for 8x-2y=12;y=4x+6 system of equations: 


  • /| 8*x-(2*y)-12 = 0| y-(4*x)-6 = 0
  • We try to solve the equation: 8*x-(2*y)-12 = 0
  • 8*x-2*y-12 = 0 // - 8*x-12
  • -2*y = -(8*x-12) // : -2
  • y = (-(8*x-12))/(-2)
  • y = (12-(8*x))/(-2)
  • We insert the solution into one of the initial equations of our system of equations
  • We get a system of equations:
  • /| (12-(8*x))/(-2)-(4*x)-6 = 0| y = (12-(8*x))/(-2)
  • (12-8*x)/(-2)-4*x-6 = 0
  • -6-6 = 0
  • -12 = 0
  • -12 = 0
  • x belongs to the empty set
  • The system of equations does not have any solution
