Solution for x+16y=9;1/4x+4y system of equations: 


  • /| x+16*y-9 = 0| (1/4)*x+4*y = 0
  • We try to solve the equation: x+16*y-9 = 0
  • x+16*y-9 = 0 // - x-9
  • 16*y = -(x-9) // : 16
  • y = (-(x-9))/16
  • y = (9-x)/16
  • We insert the solution into one of the initial equations of our system of equations
  • We get a system of equations:
  • /| 4*((9-x)/16)+(1/4)*x = 0| y = (9-x)/16
  • (4*(9-x))/16+x/4 = 0
  • 9/4 = 0
  • 9/4 = 0
  • x belongs to the empty set
  • The system of equations does not have any solution
