Question
$$2x-3^2 = 10x$$
Answer
$$ x = -\dfrac{9}{8} $$
Explanation
$$ \begin{aligned} 2x-3^2 &= 10x&& \text{simplify left side} \\[1 em]2x-9 &= 10x&& \text{move the $ \color{blue}{ 10x } $ to the left side and $ \color{blue}{ -9 }$ to the right} \\[1 em]2x-10x &= 9&& \text{simplify left side} \\[1 em]-8x &= 9&& \text{ divide both sides by $ -8 $ } \\[1 em]x &= -\frac{9}{8}&& \\[1 em] \end{aligned} $$
