Question
$$-4(5x-4)+5x+3 = 34$$
Answer
$$ x = -1 $$
Explanation
$$ \begin{aligned} -4(5x-4)+5x+3 &= 34&& \text{simplify left side} \\[1 em]-(20x-16)+5x+3 &= 34&& \\[1 em]-20x+16+5x+3 &= 34&& \\[1 em]-15x+19 &= 34&& \text{ move 19 to the right } \\[1 em]-15x &= 34-19&& \\[1 em]-15x &= 15&& \text{ divide both sides by $ -15 $ } \\[1 em]x &= -\frac{15}{15}&& \\[1 em]x &= -1&& \\[1 em] \end{aligned} $$
