$$5x+6 = 9x+30$$
Answer
$$ x = -6 $$
Explanation
$$ \begin{aligned} 5x+6 &= 9x+30&& \text{move the $ \color{blue}{ 9x } $ to the left side and $ \color{blue}{ 6 }$ to the right} \\[1 em]5x-9x &= 30-6&& \text{simplify left and right hand side} \\[1 em]-4x &= 24&& \text{ divide both sides by $ -4 $ } \\[1 em]x &= -\frac{24}{4}&& \\[1 em]x &= -6&& \\[1 em] \end{aligned} $$
