Solution for 2c+5p=16;2c+3p=8 system of equations: 


  • /| 2*c+5*p-16 = 0| 2*c+3*p-8 = 0
  • We try to solve the equation: 2*c+5*p-16 = 0
  • 2*c+5*p-16 = 0 // - 5*p-16
  • 2*c = -(5*p-16) // : 2
  • c = (-(5*p-16))/2
  • c = (16-(5*p))/2
  • We insert the solution into one of the initial equations of our system of equations
  • We get a system of equations:
  • /| 2*((16-(5*p))/2)+3*p-8 = 0| c = (16-(5*p))/2
  • (2*(16-5*p))/2+3*p-8 = 0
  • 16-2*p-8 = 0
  • 8-2*p = 0
  • 8-2*p = 0 // - 8
  • -2*p = -8 // : -2
  • p = -8/(-2)
  • p = 4
  • We insert the solution into one of the initial equations of our system of equations
  • For c = (16-(5*p))/2: 
  • c = (16-(4*5))/2
  • c = (16-20)/2
  • c = -4/2
  • c = -2
  • We get a system of equations:
  • /| c = -2| p = 4
