Solution for y=-3/5x+3;-2x-2y=4 system of equations: 


  • /| y-((-3/5)*x)-3 = 0| -2*x-(2*y)-4 = 0
  • We try to solve the equation: y-((-3/5)*x)-3 = 0
  • 3/5*x+y-3 = 0 // - 3/5*x-3
  • y = -(3/5*x-3)
  • y = 3-(3/5*x)
  • We insert the solution into one of the initial equations of our system of equations
  • We get a system of equations:
  • /| -(2*(3-(3/5*x)))-2*x-4 = 0| y = 3-(3/5*x)
  • -1*2*(3-3/5*x)-2*x-4 = 0
  • -4/5*x-6-4 = 0
  • -4/5*x-10 = 0
  • -4/5*x-10 = 0 // + 10
  • -4/5*x = 10 // : -4/5
  • x = 10/(-4/5)
  • x = -25/2
  • We insert the solution into one of the initial equations of our system of equations
  • For y = 3-(3/5*x): 
  • y = 3-(-25/2*3/5)
  • y = 3+15/2
  • y = 21/2
  • We get a system of equations:
  • /| y = 21/2| x = -25/2
