Question

3/35-(3/5+x)=2/7

cha loi ho minh nhe cam on may che

Answer 1

\(\frac{3}{35}-\left(\frac{3}{5}+x\right)=\frac{2}{7}\)

\(\Leftrightarrow\)\(\frac{3}{35}-\frac{3}{5}-x=\frac{2}{7}\)

\(\Leftrightarrow\)\(-x=\frac{2}{7}-\frac{3}{35}+\frac{3}{5}\)

\(\Leftrightarrow-x=\frac{4}{5}\)

\(\Leftrightarrow x=-\frac{4}{5}\)

Answer 2

\(\frac{3}{35}-\left(\frac{3}{5}+x\right)=\frac{2}{7}\)

\(\frac{3}{5}+x=\frac{3}{35}-\frac{2}{7}\)

\(\frac{3}{5}+x=\frac{-1}{5}\)

\(x=\frac{-1}{5}-\frac{3}{5}\)

\(x=\frac{-4}{5}\)

vậy \(x=\frac{-4}{5}\)

Answer 3

 

3/35-(3/5+x)=2/7

 =>\(\left(\frac{3}{5}+x\right)=\frac{3}{35}-\frac{2}{7}\)

=>\(\frac{3}{5}+x=-\frac{1}{5}\)

=>\(x=\frac{-1}{5}-\frac{3}{5}\)

=>\(x=\frac{-4}{5}\)
