\(14x-14=-8+9x\)
\(\begin{align} & 14x \color{red}{-14}& = & -8 \color{red}{ +9x } \\\Leftrightarrow & 14x \color{red}{-14}\color{blue}{+14-9x }
& = & -8 \color{red}{ +9x }\color{blue}{+14-9x } \\\Leftrightarrow & 14x \color{blue}{-9x }
& = & -8 \color{blue}{+14} \\\Leftrightarrow &5x
& = &6\\\Leftrightarrow & \color{red}{5}x
& = &6\\\Leftrightarrow & \frac{\color{red}{5}x}{ \color{blue}{ 5}}
& = & \frac{6}{5} \\\Leftrightarrow & \color{green}{ x = \frac{6}{5} } & & \\ & V = \left\{ \frac{6}{5} \right\} & \\\end{align}\)
