Giải thích các bước giải:
$\dfrac{-3}{2}-\dfrac{1}{4}:x=-1$
$⇔\dfrac{1}{4}:x=\dfrac{-3}{2}-(-1)$
$⇔\dfrac{1}{4}:x=\dfrac{-1}{2}$
$⇔x=\dfrac{1}{4}:\dfrac{-1}{2}$
$⇔x=\dfrac{-1}{2}$
$-1/2$
f) `(-3)/2` - `1/4` : `x` = `-1`
`1/4` : `x` =`(-3)/2` - `(-1)`
`1/4` : `x` = `(-3)/2` + `2/2`
`1/4`: `x` = `-1/2`
`x` = `1/4` : `-1/2`
`x` = `-1/2`
