Solution for Y=-1/3X+2;Y=-7/3X+7 system of equations: 


  • /| Y-((-1/3)*X)-2 = 0| Y-((-7/3)*X)-7 = 0
  • We try to solve the equation: Y-((-1/3)*X)-2 = 0
  • 1/3*X+Y-2 = 0 // - 1/3*X-2
  • Y = -(1/3*X-2)
  • Y = 2-(1/3*X)
  • We insert the solution into one of the initial equations of our system of equations
  • We get a system of equations:
  • /| 2-((-7/3)*X)-(1/3*X)-7 = 0| Y = 2-(1/3*X)
  • 2*X-5 = 0 // + 5
  • 2*X = 5 // : 2
  • X = 5/2
  • We insert the solution into one of the initial equations of our system of equations
  • For Y = 2-(1/3*X): 
  • Y = 2-(1/3*(5/2))
  • Y = 2-(1/3*5/2)
  • Y = 2-5/6
  • Y = 7/6
  • We get a system of equations:
  • /| Y = 7/6| X = 5/2
