Question
$$4(-2x-4)-3x-5 = 1$$
Answer
$$ x = -2 $$
Explanation
$$ \begin{aligned} 4(-2x-4)-3x-5 &= 1&& \text{simplify left side} \\[1 em]-8x-16-3x-5 &= 1&& \\[1 em]-11x-21 &= 1&& \text{ move -21 to the right } \\[1 em]-11x &= 1+21&& \\[1 em]-11x &= 22&& \text{ divide both sides by $ -11 $ } \\[1 em]x &= -\frac{22}{11}&& \\[1 em]x &= -2&& \\[1 em] \end{aligned} $$
