\bold{Answer}

\boxed{\bold{X \ = \ 27}}

\bold{Explanation}

  • \bold{Solve: \ \frac{2}{3}x-\frac{1}{9}x+5=20}

\bold{--------------------------}

  • \bold{Subtract \ 5 \ From \ Both \ Sides}

\bold{\frac{2}{3}x\cdot \:9-\frac{1}{9}x\cdot \:9=15\cdot \:9}

  • \bold{Simplify}

\bold{6x-x=135}

\bold{5x=135}

  • \bold{Divide \ Both \ Sides \ By \ 5}

\bold{\frac{5x}{5}=\frac{135}{5}}

  • \bold{Simplify}
