Answer 1

[Đỗ Đức Đạt]

\(\frac{12}{7}:x+\frac{2}{3}=\frac{7}{5}\)

\(\frac{12}{7}:x=\frac{7}{5}-\frac{2}{3}\)

\(\frac{12}{7}:x=\frac{21}{15}-\frac{10}{15}\)

\(\frac{12}{7}:x=\frac{11}{15}\)

         \(x=\frac{12}{7}:\frac{11}{15}\)

         \(x=\frac{12}{7}x\frac{15}{11}\)

         \(x=\frac{180}{77}\)

Answer 2

[lê văn hải]

\(\frac{12}{7}:x+\frac{2}{3}=\frac{7}{5}\)

\(\frac{12}{7}:x=\frac{7}{5}-\frac{2}{3}\)

\(\frac{12}{7}:x=\frac{11}{15}\)

\(x=\frac{12}{7}:\frac{11}{15}\)

\(x=\frac{180}{77}\)
