Question
$$7-6v = -5-8v$$
Answer
$$ v = -6 $$
Explanation
$$ \begin{aligned} 7-6v &= -5-8v&& \text{move the $ \color{blue}{ -8v } $ to the left side and $ \color{blue}{ 7 }$ to the right} \\[1 em]-6v+8v &= -5-7&& \text{simplify left and right hand side} \\[1 em]2v &= -12&& \text{ divide both sides by $ 2 $ } \\[1 em]v &= -\frac{12}{2}&& \\[1 em]v &= -6&& \\[1 em] \end{aligned} $$
