giúp mik vs ạ

Answer 1

=>12/13x=2

=>x=2:12/13=2*13/12=13/6

Answer 2

\(2\dfrac{7}{9}-\dfrac{12}{13}x=\dfrac{7}{9}\)

\(\Rightarrow\dfrac{25}{9}-\dfrac{12}{13}x=\dfrac{7}{9}\)

\(\Rightarrow\dfrac{12}{13}x=\dfrac{25}{9}-\dfrac{7}{9}\)

\(\Rightarrow\dfrac{12}{13}x=\dfrac{18}{9}\)
\(\Rightarrow\dfrac{12}{13}x=2\)

\(\Rightarrow x=2:\dfrac{12}{13}\)

\(\Rightarrow x=\dfrac{13}{6}\)
