Solution for X+3y=6;X+5y=4 system of equations: 


  • /| X+3*y-6 = 0| X+5*y-4 = 0
  • We try to solve the equation: X+3*y-6 = 0
  • X+3*y-6 = 0 // - 3*y-6
  • X = -(3*y-6)
  • X = 6-(3*y)
  • We insert the solution into one of the initial equations of our system of equations
  • We get a system of equations:
  • /| 5*y-(3*y)-4+6 = 0| X = 6-(3*y)
  • 2*y+2 = 0 // - 2
  • 2*y = -2 // : 2
  • y = -2/2
  • y = -1
  • We insert the solution into one of the initial equations of our system of equations
  • For X = 6-(3*y): 
  • X = 6-(-1*3)
  • X = 3+6
  • X = 9
