Answer 1

Answer 2

1i1/3*x= 1,6(x-1)

1i1/3x = 1,6x-1,6

1i1/3 x - 1i6/10x = -1,6

1i10/30x -1i 18/30x = -1,6

40/30x - 48/30x = -1,6

    -8/30 x = -1,6

    - 4/15x = -1,6      /(-4/15)

          x = 16/10 : 4/15

          x = 16/10 * 15/4 

          x = 4/2 * 3/1

          x = 2 * 3

          x = 6
