Solution for y-2x=0;2y+x=10 system of equations: 


  • /| y-(2*x) = 0| x+2*y-10 = 0
  • We try to solve the equation: y-(2*x) = 0
  • y-2*x = 0 // + -2*x
  • y = -(-2*x)
  • y = 2*x
  • We insert the solution into one of the initial equations of our system of equations
  • We get a system of equations:
  • /| x+2*2*x-10 = 0| y = 2*x
  • 5*x-10 = 0 // + 10
  • 5*x = 10 // : 5
  • x = 10/5
  • x = 2
  • We insert the solution into one of the initial equations of our system of equations
  • For y = 2*x: 
  • y = 2*2
  • y = 4
  • We get a system of equations:
  • /| y = 4| x = 2
