Đáp án + Giải thích các bước giải:

`1.`

`1/3 x - 3/8 = 1/8`

`<=>1/3x = 1/2`

`<=>x = 1/2 : 1/3`

`<=>x = 3/2`

Vậy `x = 3/2`

`2.`

`x + 3/4 = 1/6`

`<=>x = 1/6 - 3/4`

`<=> x = -7/12`

Vậy `x = -7/12`

`3.`

`(x + 5/6) - 7/3 = (-1)/2`

`<=> x + 5/6 = 11/6`

`<=> x = 6/6 = 1`

Vậy `x = 1`

`4.`

`x + 8,5 = 21,7`

`<=> x = 13,2`

Vậy `x = 13,2`

`5.`

`2/3 x - 1/2 = 5/6`

`<=> 2/3 x = 4/3`

`<=> x = 2`

Vậy `x = 2`

`6,`

`1 5/6  + x = 2 1/3`

`<=> 11/6 + x = 7/3`

`<=> x = 1/2`

Vậy `x = 1/2`

`7.`

`(-3)/4.(x + 2/3) = -1 1/3`

`<=> -3/4 . (x + 2/3) = -4/3`

`<=> x + 2/3 = 16/9`

`<=> x = 10/9`

Vậy `x = 10/9`

`8.`

`x + (-3)/5 = 2/7`

`<=> x = 2/7 + 3/5`

`<=> x = 31/35`

Vậy `x = 31/35`

`9.`

`2,5 x + 32,91 = 17,86`

`<=> 2,5x = -15,05`

`<=> x = -6,02`

Vậy `x = -6,02`

`10,`

`x + 3/4 = (-7)/8`

`<=>x = -7/8 - 3/4`

`<=> x = -13/8`

Vậy `x = -13/8`

`11.`

`11/5 x - 3/10 = 1/4`

`<=> 11/5 x = 11/20`

`<=> x = 1/4`

Vậy `x = 1/4`
