Answer
$$ q = 2 $$
Explanation
$$ \begin{aligned} 2q+10 &= 7q&& \text{move the $ \color{blue}{ 7q } $ to the left side and $ \color{blue}{ 10 }$ to the right} \\[1 em]2q-7q &= -10&& \text{simplify left side} \\[1 em]-5q &= -10&& \text{ divide both sides by $ -5 $ } \\[1 em]q &= \frac{-10}{-5}&& \\[1 em]q &= 2&& \\[1 em] \end{aligned} $$
