Solution for 6c+5l=2270;5c+4l=1880 system of equations: 


  • /| 6*c+5*l-2270 = 0| 5*c+4*l-1880 = 0
  • We try to solve the equation: 6*c+5*l-2270 = 0
  • 6*c+5*l-2270 = 0 // - 5*l-2270
  • 6*c = -(5*l-2270) // : 6
  • c = (-(5*l-2270))/6
  • c = (2270-(5*l))/6
  • We insert the solution into one of the initial equations of our system of equations
  • We get a system of equations:
  • /| 5*((2270-(5*l))/6)+4*l-1880 = 0| c = (2270-(5*l))/6
  • (5*(2270-5*l))/6+4*l-1880 = 0
  • 5675/3-1/6*l-1880 = 0
  • 35/3-1/6*l = 0
  • 35/3-1/6*l = 0 // - 35/3
  • -1/6*l = -35/3 // : -1/6
  • l = -35/3/(-1/6)
  • l = 70
  • We insert the solution into one of the initial equations of our system of equations
  • For c = (2270-(5*l))/6: 
  • c = (2270-(5*70))/6
  • c = (2270-350)/6
  • c = 1920/6
  • c = 320
  • We get a system of equations:
  • /| c = 320| l = 70
