Which of the systems of linear equations have the same solutions:

  • A={x+5y=17x+4y=14A = \begin{cases} x + 5y= 17\\ x + 4y= 14\\ \end{cases}
  • B={5x+3y=194x−2y=2B = \begin{cases} 5x + 3y= 19\\ 4x - 2y= 2\\ \end{cases}
  • C={5x−2y=47x+2y=7C = \begin{cases} 5x -2y= 4\\ 7x + 2y= 7\\ \end{cases}
  • D={7x+2y=74x−2y=2D = \begin{cases} 7x + 2y= 7\\ 4x - 2y= 2\\ \end{cases}
