\(a,\frac{1313}{2828}+x=\frac{2323}{4646}\)
\(\frac{13}{28}+x=\frac{1}{2}\)
\(x=\frac{1}{2}-\frac{13}{28}=\frac{1}{28}\)
\(b,\frac{5}{7}+\frac{x}{35}=\frac{4}{5}\)
\(\frac{x}{35}=\frac{4}{5}-\frac{5}{7}=\frac{3}{35}\)
\(\Rightarrow x=3\)
\(c,\frac{23}{69}-x=\frac{17}{153}\)
\(\frac{1}{3}-x=\frac{1}{9}\)
\(x=\frac{1}{3}-\frac{1}{9}=\frac{2}{9}\)
