Step-by-step explanation:

5\color{red}{x}+\color{blue}{168}=

5x+168=

\,\,\color{purple}{743}

743

-\color{blue}{168}\phantom{=}

−168=

\,\,-\color{blue}{168}

−168

Subtract 168 from both sides

5\color{red}{x}=

5x=

\,\,575

575

\frac{5\color{red}{x}}{5}=

5

5x

=

\,\,\frac{575}{5}

5

575

Divide both sides by 5

\color{red}{x}=

x=

\,\,\boxed{\color{red}{115}}
