Solution for -4x+2y=-17;-8x-2y=-10 system of equations: 


  • /| 2*y-4*x+17 = 0| 10-8*x-(2*y) = 0
  • We try to solve the equation: 2*y-4*x+17 = 0
  • 2*y-4*x+17 = 0 // - 17-4*x
  • 2*y = -(17-4*x) // : 2
  • y = (-(17-4*x))/2
  • We insert the solution into one of the initial equations of our system of equations
  • We get a system of equations:
  • /| 10-(2*((-(17-4*x))/2))-8*x = 0| y = (-(17-4*x))/2
  • (-1*2*(4*x-17))/2-8*x+10 = 0
  • 10-12*x+17 = 0
  • 27-12*x = 0
  • 27-12*x = 0 // - 27
  • -12*x = -27 // : -12
  • x = -27/(-12)
  • x = 9/4
  • We insert the solution into one of the initial equations of our system of equations
  • For y = (-(17-4*x))/2: 
  • y = (-(17-4*9/4))/2
  • y = (-(17-9))/2
  • y = -8/2
  • y = -4
  • We get a system of equations:
  • /| y = -4| x = 9/4
