Tìm x

\(\frac{x-1}{9}=\frac{8}{3}\)

 

Answer 1

\(\frac{x-1}{9}=\frac{8}{3}\Rightarrow\frac{x-1}{9}=\frac{8.3}{3.3}\Rightarrow\frac{x-1}{9}=\frac{24}{9}\Rightarrow\frac{x}{9}=\frac{24+1}{9}\Rightarrow\frac{x}{9}=\frac{25}{9}\Rightarrow x=25\)

Answer 2

\(\frac{x-1}{9}=\frac{8}{3}\)

\(x-1=\frac{8.9}{3}\)

\(x-1=\frac{72}{3}\)

\(x-1=24\)

\(x=24-1\)

\(x=23\)
