\(\frac{x}{27}-\frac{2}{9}=\frac{6}{18}\)
\(\frac{x}{27}-\frac{2}{9}=\frac{1}{3}\)
\(\frac{x}{27}=\frac{1}{3}+\frac{2}{9}\)
\(\frac{x}{27}=\frac{3}{9}+\frac{2}{9}\)
\(\frac{x}{27}=\frac{5}{9}\)
\(\Rightarrow x\div27=\frac{5}{9}\)
\(\Rightarrow x=\frac{5}{9}\times27\)
\(\Rightarrow x=15\)

\(\frac{x}{27}-\frac{2}{9}=\frac{6}{18}\)
\(\frac{x}{27}=\frac{6}{18}+\frac{2}{9}\)
\(\frac{x}{27}=\frac{5}{9}\)
\(\Rightarrow x.9=5.27\)
\(\Rightarrow x.9=135\)
\(\Rightarrow x=15\)
Vậy x=15
\(\frac{x}{27}-\frac{2}{9}=\frac{6}{18}\)
\(\frac{x}{27}=\frac{6}{18}+\frac{2}{9}\)
\(\frac{x}{27}=\frac{3}{9}+\frac{2}{9}\)
\(\frac{x}{27}=\frac{5}{9}\)
\(x=\frac{5}{9}\times27\)
\(x=15\)
\(\frac{x}{27}-\frac{2}{9}=\frac{6}{18}\)
\(\frac{x}{27}=\frac{6}{18}+\frac{2}{9}\)
\(\frac{x}{27}=\frac{5}{9}\)
x \(=\frac{5.27}{9}\)
x = 15
