Solution for 2x-11y=7;3x-9y=7 system of equations:


  • /| 2*x-(11*y)-7 = 0| 3*x-(9*y)-7 = 0
  • We try to solve the equation: 2*x-(11*y)-7 = 0
  • 2*x-11*y-7 = 0 / - 2*x-7
  • -11*y = -(2*x-7) / : -11
  • y = (-(2*x-7))/(-11)
  • y = (7-(2*x))/(-11)
  • We insert the solution into one of the initial equations of our system of equations
  • We get a system of equations:
  • /| 3*x-(9*((7-(2*x))/(-11)))-7 = 0| y = (7-(2*x))/(-11)
  • (-1*9*(7-2*x))/(-11)+3*x-7 = 0
  • 15/11*x-7+63/11 = 0
  • 15/11*x-14/11 = 0
  • 15/11*x-14/11 = 0 / + 14/11
  • 15/11*x = 14/11 / : 15/11
  • x = 14/11/15/11
  • x = 14/15
  • We insert the solution into one of the initial equations of our system of equations
  • For y = (7-(2*x))/(-11):
  • y = (7-(14/15*2))/(-11)
  • y = (7-28/15)/(-11)
  • y = 77/15/(-11)
  • y = -7/15
  • We get a system of equations:
  • /| y = -7/15| x = 14/15
