$$v+\frac{9}{15} = 0$$

$$ \begin{aligned} v+\frac{9}{15} &= 0&& \text{multiply ALL terms by } \color{blue}{ 15 }. \\[1 em]15v+15\cdot\frac{9}{15} &= 15\cdot0&& \text{cancel out the denominators} \\[1 em]15v+9 &= 0&& \text{ move the constants to the right } \\[1 em]15v &= -9&& \text{ divide both sides by $ 15 $ } \\[1 em]v &= -\frac{9}{15}&& \\[1 em]v &= -\frac{3}{5}&& \\[1 em] \end{aligned} $$
