Question

Answer 1

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

\(\Leftrightarrow x=\dfrac{3}{5}+\dfrac{4}{7}=\dfrac{21}{35}+\dfrac{20}{35}=\dfrac{41}{35}\)

Answer 2

\(-\dfrac{4}{7}-\dfrac{3}{5}=-2x+x\Leftrightarrow x=\dfrac{4}{7}+\dfrac{3}{5}=\dfrac{41}{35}\)

Answer 3

e) \(-\dfrac{4}{7}-x=\dfrac{3}{5}-2x\)

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

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

\(x=\dfrac{3}{5}+\dfrac{4}{7}\)

\(x=\dfrac{21}{35}+\dfrac{20}{35}\)

\(x=\dfrac{41}{35}\)

Answer 4

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

<=> \(2x-x=\dfrac{3}{5}+\dfrac{4}{7}\)

<=> x = \(\dfrac{41}{35}\)
