\(7x+4=-6-10x\)
\(\begin{align} & 7x \color{red}{+4}& = & -6 \color{red}{ -10x } \\\Leftrightarrow & 7x \color{red}{+4}\color{blue}{-4+10x }
& = & -6 \color{red}{ -10x }\color{blue}{-4+10x } \\\Leftrightarrow & 7x \color{blue}{+10x }
& = & -6 \color{blue}{-4} \\\Leftrightarrow &17x
& = &-10\\\Leftrightarrow & \color{red}{17}x
& = &-10\\\Leftrightarrow & \frac{\color{red}{17}x}{ \color{blue}{ 17}}
& = & \frac{-10}{17} \\\Leftrightarrow & \color{green}{ x = \frac{-10}{17} } & & \\ & V = \left\{ \frac{-10}{17} \right\} & \\\end{align}\)
