\(-\dfrac{4}{7}-x=\dfrac{3}{5}-2x\)
\(\Leftrightarrow x=\dfrac{3}{5}+\dfrac{4}{7}=\dfrac{21}{35}+\dfrac{20}{35}=\dfrac{41}{35}\)
\(-\dfrac{4}{7}-\dfrac{3}{5}=-2x+x\Leftrightarrow x=\dfrac{4}{7}+\dfrac{3}{5}=\dfrac{41}{35}\)
e) \(-\dfrac{4}{7}-x=\dfrac{3}{5}-2x\)
\(-\dfrac{4}{7}-x+2x=\dfrac{3}{5}\)
\(-\dfrac{4}{7}+x=\dfrac{3}{5}\)
\(x=\dfrac{3}{5}+\dfrac{4}{7}\)
\(x=\dfrac{21}{35}+\dfrac{20}{35}\)
\(x=\dfrac{41}{35}\)
\(-\dfrac{4}{7}-x=\dfrac{3}{5}-2x\)
<=> \(2x-x=\dfrac{3}{5}+\dfrac{4}{7}\)
<=> x = \(\dfrac{41}{35}\)
