Đáp án:
`x = 2`
Giải thích các bước giải:
$c)$ `10/3 × 1/2 - (1/2 × x - 1/3) + 1/5 = 3/5 : 1/2`
`=>` `5/3 - (1/2 × x - 1/3) + 1/5 = 6/5`
`=>` `5/3 - (1/2 × x - 1/3) = 6/5 - 1/5`
`=>` `5/3 - (1/2 × x - 1/3) = 1`
`=>` `(1/2 × x - 1/3) = 5/3 - 1`
`=>` `1/2 × x - 1/3 = 2/3`
`=>` `1/2 × x = 2/3 + 1/3`
`=>` `1/2 × x = 1`
`=>` `x = 2`
Vậy `x = 2`
