\(13x+4=14-4x\)
\(\begin{align} & 13x \color{red}{+4}& = & 14 \color{red}{ -4x } \\\Leftrightarrow & 13x \color{red}{+4}\color{blue}{-4+4x }
& = & 14 \color{red}{ -4x }\color{blue}{-4+4x } \\\Leftrightarrow & 13x \color{blue}{+4x }
& = & 14 \color{blue}{-4} \\\Leftrightarrow &17x
& = &10\\\Leftrightarrow & \color{red}{17}x
& = &10\\\Leftrightarrow & \frac{\color{red}{17}x}{ \color{blue}{ 17}}
& = & \frac{10}{17} \\\Leftrightarrow & \color{green}{ x = \frac{10}{17} } & & \\ & V = \left\{ \frac{10}{17} \right\} & \\\end{align}\)
