\(2x+14=-8+5x\)
\(\begin{align} & 2x \color{red}{+14}& = & -8 \color{red}{ +5x } \\\Leftrightarrow & 2x \color{red}{+14}\color{blue}{-14-5x }
& = & -8 \color{red}{ +5x }\color{blue}{-14-5x } \\\Leftrightarrow & 2x \color{blue}{-5x }
& = & -8 \color{blue}{-14} \\\Leftrightarrow &-3x
& = &-22\\\Leftrightarrow & \color{red}{-3}x
& = &-22\\\Leftrightarrow & \frac{\color{red}{-3}x}{ \color{blue}{ -3}}
& = & \frac{-22}{-3} \\\Leftrightarrow & \color{green}{ x = \frac{22}{3} } & & \\ & V = \left\{ \frac{22}{3} \right\} & \\\end{align}\)
