\(-5x-10=-14+x\)
\(\begin{align} & -5x \color{red}{-10}& = & -14 \color{red}{ +x } \\\Leftrightarrow & -5x \color{red}{-10}\color{blue}{+10-x }
& = & -14 \color{red}{ +x }\color{blue}{+10-x } \\\Leftrightarrow & -5x \color{blue}{-x }
& = & -14 \color{blue}{+10} \\\Leftrightarrow &-6x
& = &-4\\\Leftrightarrow & \color{red}{-6}x
& = &-4\\\Leftrightarrow & \frac{\color{red}{-6}x}{ \color{blue}{ -6}}
& = & \frac{-4}{-6} \\\Leftrightarrow & \color{green}{ x = \frac{2}{3} } & & \\ & V = \left\{ \frac{2}{3} \right\} & \\\end{align}\)
