Solution for x-2y+16;8x+3y-62 system of equations: 


  • /| x-(2*y)+16 = 0| 8*x+3*y-62 = 0
  • We try to solve the equation: x-(2*y)+16 = 0
  • x-2*y+16 = 0 // - x+16
  • -2*y = -(x+16) // : -2
  • y = (-(x+16))/(-2)
  • y = (x+16)/2
  • We insert the solution into one of the initial equations of our system of equations
  • We get a system of equations:
  • /| 3*((x+16)/2)+8*x-62 = 0| y = (x+16)/2
  • (3*(x+16))/2+8*x-62 = 0
  • 19/2*x-62+24 = 0
  • 19/2*x-38 = 0
  • 19/2*x-38 = 0 // + 38
  • 19/2*x = 38 // : 19/2
  • x = 38/19/2
  • x = 4
  • We insert the solution into one of the initial equations of our system of equations
  • For y = (x+16)/2: 
  • y = (4+16)/2
  • y = 20/2
  • y = 10
  • We get a system of equations:
  • /| y = 10| x = 4
