Question

\(\dfrac{2}{7}x+1:\left(-7\right)=\dfrac{-1}{28}\)

Answer 1

\(\dfrac{2}{7}x+1:\left(-7\right)=\dfrac{-1}{28}\)

\(\dfrac{2}{7}x-\dfrac{1}{7}=\dfrac{-1}{28}\)

\(\dfrac{2}{7}x=\dfrac{-1}{28}+\dfrac{1}{7}\)

\(\dfrac{2}{7}x=\dfrac{3}{28}\)

\(x=\dfrac{3}{28}:\dfrac{2}{7}\)

\(x=\dfrac{3}{8}\)

Answer 2

\(\dfrac{2}{7}x+\dfrac{-1}{7}=\dfrac{-1}{28}\)

\(\dfrac{2}{7}x=\dfrac{-1}{28}-\dfrac{-1}{7}\)

\(\dfrac{2}{7}x=\dfrac{3}{28}\)

\(x=\dfrac{3}{28}:\dfrac{2}{7}\)

\(x=\dfrac{3}{8}\)
