Solution for x+y=1520;x=y-160 system of equations: 


  • /| x+y-1520 = 0| x-y+160 = 0
  • We try to solve the equation: x+y-1520 = 0
  • x+y-1520 = 0 // - x-1520
  • y = -(x-1520)
  • y = 1520-x
  • We insert the solution into one of the initial equations of our system of equations
  • We get a system of equations:
  • /| x+x-1520+160 = 0| y = 1520-x
  • 2*x-1360 = 0 // + 1360
  • 2*x = 1360 // : 2
  • x = 1360/2
  • x = 680
  • We insert the solution into one of the initial equations of our system of equations
  • For y = 1520-x: 
  • y = 1520-680
  • y = 840
  • We get a system of equations:
  • /| y = 840| x = 680
