3/x+15=15%
3/x =15%-15
3/x = -14,85
x = -14,85x3
x = -44,55.
Ủng hộ nhé.
\(\frac{3}{x}+15=\frac{3}{20}\)
\(\frac{3}{x}=\frac{3}{20}-\frac{300}{20}=\frac{-297}{20}\)
\(x=3.\frac{20}{-297}=\frac{-20}{99}\)
\(\frac{3}{x}+15=\frac{15}{100}\)
\(=>\frac{3}{x}=-14,85\)
\(=>x=\frac{-20}{99}\)
Vậy \(x=\frac{-20}{99}\)
