Question

`(x:1/4+3/2)*2/7=(-1)/7`

Answer 1

\(=>x:\dfrac{1}{4}=\left(-\dfrac{1}{7}:\dfrac{2}{7}\right)-\dfrac{3}{2}=-\dfrac{1}{2}-\dfrac{3}{2}=-\dfrac{4}{2}=-2\)

\(=>x=\dfrac{1}{4}\cdot\left(-2\right)=-\dfrac{2}{4}=-\dfrac{1}{2}\)

Answer 2

\(\Leftrightarrow x:\dfrac{1}{4}+\dfrac{3}{2}=-\dfrac{1}{7}:\dfrac{2}{7}\)

\(\Leftrightarrow x:\dfrac{1}{4}+\dfrac{3}{2}=-\dfrac{1}{2}\)

\(\Leftrightarrow x:\dfrac{1}{4}=-\dfrac{1}{2}-\dfrac{3}{2}\)

\(\Leftrightarrow x:\dfrac{1}{4}=-\dfrac{4}{2}\)

\(\Leftrightarrow x=-\dfrac{4}{2}.\dfrac{1}{4}\)

\(\Leftrightarrow x=-\dfrac{4}{8}\)

\(\Leftrightarrow x=-\dfrac{1}{2}\)

Answer 3

-1/2
