Question
$$-3(-2x-3)-3x+4 = -2$$
Answer
$$ x = -5 $$
Explanation
$$ \begin{aligned} -3(-2x-3)-3x+4 &= -2&& \text{simplify left side} \\[1 em]-(-6x-9)-3x+4 &= -2&& \\[1 em]6x+9-3x+4 &= -2&& \\[1 em]3x+13 &= -2&& \text{ move 13 to the right } \\[1 em]3x &= -2-13&& \\[1 em]3x &= -15&& \text{ divide both sides by $ 3 $ } \\[1 em]x &= -\frac{15}{3}&& \\[1 em]x &= -5&& \\[1 em] \end{aligned} $$
