Đáp án + Giải thích các bước giải:
a)
`x + \frac{1}{3} = \frac{2}{5}`
`x = \frac{2}{5} - \frac{1}{3}`
`x = \frac{1}{15}`
b)
`x - 10% = -1\frac{5}{6}`
`x = \frac{-11}{6} + \frac{1}{10}`
`x = \frac{-26}{15}`
c)
`x : 2\frac{2}{3} = -0,5`
`x = -0,5 . \frac{8}{3}`
`x = \frac{-4}{3}`
d)
`3x = \frac{5}{12}`
`x = \frac{5}{12} : 3`
`x= \frac{5}{36}`
e)
`\frac{-3}{2}x + \frac{2}{3}x = -1`
`\frac{-5}{6}x = -1`
`x = \frac{6}{5}`
f)
`|x-1| = \frac{1}{2}`
`x - 1= ±\frac{1}{2}`
`x = \frac{3}{2}`
`x = \frac{-1}{2}`
