Question

Answer 1

\(2,5x=-1,5-\dfrac{4}{7}\)

\(2,5x=-\dfrac{29}{14}\)

\(x=-\dfrac{29}{14}:2,5\)

\(x=\dfrac{-29}{35}\)

Answer 2

`2,5 x + 4/7 = -1,5`

`2,5 x + 4/7 = -3/2`

`2,5 x = -3/2 - 4/7`

`2,5 x = -29/14`

`x=-29/14 : 2,5`

`x=-29,14 : 5/2`

`x=-29/14 xx 2/5`

`x=-29/35`

Vậy `x=-29/35`
