Solution for y=54+5x;y=84+2x system of equations: 


  • /| y-(5*x)-54 = 0| y-(2*x)-84 = 0
  • We try to solve the equation: y-(5*x)-54 = 0
  • y-5*x-54 = 0 // + -5*x-54
  • y = -(-5*x-54)
  • y = 54-(-5*x)
  • We insert the solution into one of the initial equations of our system of equations
  • We get a system of equations:
  • /| 54-(2*x)-(-5*x)-84 = 0| y = 54-(-5*x)
  • 3*x-30 = 0 // + 30
  • 3*x = 30 // : 3
  • x = 30/3
  • x = 10
  • We insert the solution into one of the initial equations of our system of equations
  • For y = 54-(-5*x): 
  • y = 54-(-5*10)
  • y = 50+54
  • y = 104
  • We get a system of equations:
  • /| y = 104| x = 10
