2x+9y=5 multiply by -5  and will get -10x-45y=-25  addition
5x+3y=6 multiply by 2                       10x+6y=12
                                                       ----------------
                                                           0   -39y=-13
                                                                      y= -13/-39
                                                                      y= 1/3
2x+9(1/3)=5
2x+9/3=5
2x+3=5
2x=2
 x=1

  x=1
  y=1/3
