let the added twice number be = 2x \begin{gathered}\implies 2x- \frac{7}{5}+x= \frac{3}{7} \\ \implies \frac{-14}{5}+x=\frac{3}{7} \\ \implies x= \frac{3}{7}+ \frac{14}{5} \\ \implies x= \frac{15+98}{35} \\ \implies x= \frac{113}{35}\end{gathered} ⟹2x− 5 7 +x= 7 3 ⟹ 5 −14 +x= 7 3 ⟹x= 7 3 + 5 14 ⟹x= 35 15+98 ⟹x= 35 113
