\(\frac{X}{126}=\frac{-7}{24}.\frac{-6}{11}\)
\(\frac{X}{126}=\frac{42}{264}\)
\(\frac{X}{126}=\frac{7}{44}\)
\(X=\frac{7}{44}.126=\frac{882}{44}=\frac{441}{22}\)
Vậy x = 441/22
\(\frac{x}{126}=\frac{-7}{24}.\frac{-6}{11}\)
\(\Rightarrow\frac{x}{126}=\frac{7}{44}\)
\(\Rightarrow x.44=126.7\)
\(\Rightarrow x.44=882\)
\(\Rightarrow x=882:44\)
\(\Rightarrow x=\frac{441}{22}\)
