Question
$$3x-23(x-5) = 0$$
Answer
$$ x = \dfrac{23}{4} $$
Explanation
$$ \begin{aligned} 3x-23(x-5) &= 0&& \text{simplify left side} \\[1 em]3x-(23x-115) &= 0&& \\[1 em]3x-23x+115 &= 0&& \\[1 em]-20x+115 &= 0&& \text{ move the constants to the right } \\[1 em]-20x &= -115&& \text{ divide both sides by $ -20 $ } \\[1 em]x &= \frac{-115}{-20}&& \\[1 em]x &= \frac{23}{4}&& \\[1 em] \end{aligned} $$
