Question

\(\left(-0,75.x+\dfrac{5}{2}\right).\dfrac{4}{7}-\left(-\dfrac{1}{3}\right)=\dfrac{-5}{6}\)

Answer 1

\(\Leftrightarrow\left(\dfrac{-3}{4}x+\dfrac{5}{2}\right)\cdot\dfrac{4}{7}=\dfrac{-5}{6}-\dfrac{1}{3}=\dfrac{-4}{3}\)

\(\Leftrightarrow-\dfrac{3}{4}x+\dfrac{5}{2}=\dfrac{-4}{3}:\dfrac{4}{7}=\dfrac{-7}{3}\)

=>-3/4x=-29/6

hay x=58/9

Answer 2

`(-0,75.x+5/2). 4/7-(-1/3)=[-5]/6`

`(-3/4 .x+5/2). 4/7=-7/6`

`-3/4 .x+5/2=-49/24`

`-3/4 .x=-109/24`

`x=109/18`
