Solution for 2y=5x+2;y=(5/2)x+1 system of equations: 


  • /| 2*y-(5*x)-2 = 0| y-((5/2)*x)-1 = 0
  • We try to solve the equation: 2*y-(5*x)-2 = 0
  • 2*y-5*x-2 = 0 // + -5*x-2
  • 2*y = -(-5*x-2) // : 2
  • y = (-(-5*x-2))/2
  • y = (2-(-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-(-5*x))/2-((5/2)*x)-1 = 0| y = (2-(-5*x))/2
  • (5*x+2)/2+(-5*x)/2-1 = 0
  • 1-1 = 0
  • 0 = 0
  • The system of equations has infinitely many solutions
