$$-42/(-35+42)+(-14+9 \times 7)/(-5-2)-8 \times (-9)$$
$59$
$$\frac{-42}{7}+\frac{-14+9\times 7}{-5-2}-8\left(-9\right)$$
$$-6+\frac{-14+9\times 7}{-5-2}-8\left(-9\right)$$
$$-6+\frac{-14+63}{-5-2}-8\left(-9\right)$$
$$-6+\frac{49}{-5-2}-8\left(-9\right)$$
$$-6+\frac{49}{-7}-8\left(-9\right)$$
$$-6-7-8\left(-9\right)$$
$$-13-8\left(-9\right)$$
$$-13-\left(-72\right)$$
$$-13+72$$
$$59$$
