Solution for y=-6x-16;y=6x+20 system of equations: 


  • /| y-(-6*x)+16 = 0| y-(6*x)-20 = 0
  • We try to solve the equation: y-(-6*x)+16 = 0
  • 6*x+y+16 = 0 // - 6*x+16
  • y = -(6*x+16)
  • We insert the solution into one of the initial equations of our system of equations
  • We get a system of equations:
  • /| -(6*x)-(6*x)-20-16 = 0| y = -(6*x+16)
  • -12*x-36 = 0 // + 36
  • -12*x = 36 // : -12
  • x = 36/(-12)
  • x = -3
  • We insert the solution into one of the initial equations of our system of equations
  • For y = -(6*x+16): 
  • y = -(16-3*6)
  • y = -(16-18)
  • y = 2
  • We get a system of equations:
  • /| y = 2| x = -3
