Solution for 2y=12x/5-12;2y=4x+16 system of equations: 


  • /| 2*y-((12*x)/5)+12 = 0| 2*y-(4*x)-16 = 0
  • We try to solve the equation: 2*y-((12*x)/5)+12 = 0
  • 2*y-12/5*x+12 = 0 // - 12-12/5*x
  • 2*y = -(12-12/5*x) // : 2
  • y = (-(12-12/5*x))/2
  • We insert the solution into one of the initial equations of our system of equations
  • We get a system of equations:
  • /| 2*((-(12-12/5*x))/2)-(4*x)-16 = 0| y = (-(12-12/5*x))/2
  • (2*(12/5*x-12))/2-4*x-16 = 0
  • -8/5*x-16-12 = 0
  • -8/5*x-28 = 0
  • -8/5*x-28 = 0 // + 28
  • -8/5*x = 28 // : -8/5
  • x = 28/(-8/5)
  • x = -35/2
  • We insert the solution into one of the initial equations of our system of equations
  • For y = (-(12-12/5*x))/2: 
  • y = (-(12-35/2*(-12/5)))/2
  • y = (-(12/5*35/2+12))/2
  • y = (-(12+42))/2
  • y = -54/2
  • y = -27
  • We get a system of equations:
  • /| y = -27| x = -35/2
