\(14x-5=5-11x\)
\(\begin{align} & 14x \color{red}{-5}& = & 5 \color{red}{ -11x } \\\Leftrightarrow & 14x \color{red}{-5}\color{blue}{+5+11x }
& = & 5 \color{red}{ -11x }\color{blue}{+5+11x } \\\Leftrightarrow & 14x \color{blue}{+11x }
& = & 5 \color{blue}{+5} \\\Leftrightarrow &25x
& = &10\\\Leftrightarrow & \color{red}{25}x
& = &10\\\Leftrightarrow & \frac{\color{red}{25}x}{ \color{blue}{ 25}}
& = & \frac{10}{25} \\\Leftrightarrow & \color{green}{ x = \frac{2}{5} } & & \\ & V = \left\{ \frac{2}{5} \right\} & \\\end{align}\)
