Solution for y=4/3x-8;y=-8/7x+8 system of equations: 


  • /| y-((4/3)*x)+8 = 0| y-((-8/7)*x)-8 = 0
  • We try to solve the equation: y-((4/3)*x)+8 = 0
  • y-4/3*x+8 = 0 // - 8-4/3*x
  • y = -(8-4/3*x)
  • We insert the solution into one of the initial equations of our system of equations
  • We get a system of equations:
  • /| -((-8/7)*x)-(-4/3*x)-8-8 = 0| y = -(8-4/3*x)
  • 52/21*x-16 = 0 // + 16
  • 52/21*x = 16 // : 52/21
  • x = 16/52/21
  • x = 84/13
  • We insert the solution into one of the initial equations of our system of equations
  • For y = -(8-4/3*x): 
  • y = -(8-4/3*84/13)
  • y = -(8-112/13)
  • y = 8/13
  • We get a system of equations:
  • /| y = 8/13| x = 84/13
