1 1/7 x x = 8/7 x-8,01=1,99 x : 4 x 3,5 + 6,3 x : 3,5 = 17,8 + 5,4 x + 1/8 = 1/2 – 1/3 x – 3 1/2 = 2 1/5 làm hết nha

1. `a) 1 1/7 × x = 8/7`

   `x = 8/7 : 1 1/7`

   `x = 8/7 : 8/7`

   `x=1`

   `b) x-8,01=1,99`

   `x=1,99+8,01`

   `x=10`

   c) Chưa Rõ

   `d) x:3,5=17,8+5,4`

   `x:3,5=23,2`

   `x=23,2×3,5`

   `x=81,2`

   `e) x+1/8=1/2-1/3`

   `x+1/8=3/6-2/6`

   `x+1/8=1/6`

   `x=1/6-1/8`

   `x=8/48-6/48`

   `x=2/48`

   `x=1/24`

   `f) x-3 1/2=2 1/5`

   `x=2 1/5+3 1/4`

   `x=11/5+13/4`

   `x=109/20`
