Question

Answer 1

`-3/4(8/9-x)+3/5=-2/3 . 1/2`

`-3/4(8/9-x)+3/5=-1/3`

`-3/4(8/9-x)=-1/3-3/5`

`-3/4(8/9-x)=-14/15`

`8/9-x=-14/15 . (-4/3)`

`8/9-x=56/45`

`x=8/9-56/45`

`x=-16/45`

Answer 3

\(-\dfrac{3}{4}\left(\dfrac{8}{9}-x\right)=-\dfrac{1}{3}-\dfrac{3}{5}=\dfrac{-14}{15}\Leftrightarrow\dfrac{8}{9}-x=\dfrac{56}{45}\Leftrightarrow x=-\dfrac{16}{45}\)
