Solution for 45X-10Y=20;9X=2Y+4 system of equations: 


  • /| 45*X-(10*Y)-20 = 0| 9*X-(2*Y)-4 = 0
  • We try to solve the equation: 45*X-(10*Y)-20 = 0
  • 45*X-10*Y-20 = 0 // - 45*X-20
  • -10*Y = -(45*X-20) // : -10
  • Y = (-(45*X-20))/(-10)
  • Y = (20-(45*X))/(-10)
  • We insert the solution into one of the initial equations of our system of equations
  • We get a system of equations:
  • /| 9*X-(2*((20-(45*X))/(-10)))-4 = 0| Y = (20-(45*X))/(-10)
  • (-1*2*(20-45*X))/(-10)+9*X-4 = 0
  • 4-4 = 0
  • 0 = 0
  • The system of equations has infinitely many solutions
