Solution for y=2x-5;6x-y=-3 system of equations: 


  • /| y-(2*x)+5 = 0| 6*x-y+3 = 0
  • We try to solve the equation: y-(2*x)+5 = 0
  • y-2*x+5 = 0 // - 5-2*x
  • y = -(5-2*x)
  • We insert the solution into one of the initial equations of our system of equations
  • We get a system of equations:
  • /| 6*x-2*x+3+5 = 0| y = -(5-2*x)
  • 4*x+8 = 0 // - 8
  • 4*x = -8 // : 4
  • x = -8/4
  • x = -2
  • We insert the solution into one of the initial equations of our system of equations
  • For y = -(5-2*x): 
  • y = -(5-2*(-2))
  • y = -(2*2+5)
  • y = -(4+5)
  • y = -9
  • We get a system of equations:
  • /| y = -9| x = -2
