Question
$$4-5x = 3x+28$$
Answer
$$ x = -3 $$
Explanation
$$ \begin{aligned} 4-5x &= 3x+28&& \text{move the $ \color{blue}{ 3x } $ to the left side and $ \color{blue}{ 4 }$ to the right} \\[1 em]-5x-3x &= 28-4&& \text{simplify left and right hand side} \\[1 em]-8x &= 24&& \text{ divide both sides by $ -8 $ } \\[1 em]x &= -\frac{24}{8}&& \\[1 em]x &= -3&& \\[1 em] \end{aligned} $$
