Nilai x yang memenuhi sistem persamaan 5(x-2y)-3(x-3y)=-1 Dan 3(y-x) + 2+x-y)=2 adalah A.-40 B.-1 C.1 D.3 Tolong jalan ya

5(x-2y) - 3(x-3y) =  -1  <---> 5(x-2y) - 3(x-3y) = -1
                                            5x - 10y - 3x + 9y = -1
                                              2x -y = -1  ..............(i)
3(y-x) + 2(x-y) = 2   <--> 3(y-x) + 2(x-y) = 2
                                        3y -3x + 2x -2y = 2
                                          y - x =2
                                         -x + y = 2 ..........(ii)
eliminasi y
2x - y = -1
-x +y  = 2
-------------  +
 x    = 1 ....................(C)
