x is missing

jhonyy9 · Answer

0,3x -0,2y =4  / x 10 --- 3x -2y =40
0,4x +0,5y = -55/17
0,3x -0,2y =4
-------------
0,1x +0,7y = -55/17 -4
1,7x +11,9y =-55 -68
1,7x +11,9y = -123 / x 10
17x + 119y = -1230

3x-2y =40 --- x=(40+2y)/3
17(40+2y)/3 +119y = -1230
   680 +34y + 357y = - 3690
 391y = - 4370
           4370
  y = - -------
             391

40 + 2(- 4370/391)       40-8740      - 8700
than x = ------------------ = ---------- = -------
