himpunan penyelesaian dari 2x+5y=9danx+3y=-1adalah

2x+5y=9
x+3y= -1

eliminasi x
2x+5y = 9 |*1| 2x+5y = 9
x+3y = -1 |*2|  2x+6y = -2
                       ---------------  -
                             -y  = 11
                              y  = -11
subtitusi nilai y = -11 ke persamaan x+3y= -1
<---> x +3(-11) = -1
         x - 33 = -1
                x = -1 + 33
                x = 32
  Hp: {(32, -11)}
