\(\frac{x}{468}=-\frac{7}{13}\times\frac{5}{9}\)
\(\Leftrightarrow\frac{x}{468}=-\frac{35}{117}\)
\(\Leftrightarrow x.117=-35\times468\)
\(\Leftrightarrow x.117=-14976\)
\(\Leftrightarrow x=-128\)
Vậy \(x=-128\)
x/468=-7/13x 5/9
x/468=-35/117
=>x.117=-35.468
=>x.117=-16380
x=-16380:117
x=-140
Vậy x= -140.
