$$-2-7(2x-5) = 89$$
Answer
$$ x = -4 $$
Explanation
$$ \begin{aligned} -2-7(2x-5) &= 89&& \text{simplify left side} \\[1 em]-2-(14x-35) &= 89&& \\[1 em]-2-14x+35 &= 89&& \\[1 em]-14x+33 &= 89&& \text{ move 33 to the right } \\[1 em]-14x &= 89-33&& \\[1 em]-14x &= 56&& \text{ divide both sides by $ -14 $ } \\[1 em]x &= -\frac{56}{14}&& \\[1 em]x &= -4&& \\[1 em] \end{aligned} $$
