Explicación paso a paso:

$3\left[7-\left(1-4\right)\right]-12/\left(-5+7-8+10\right)\left(-3-5-4\right)\\\\\mathrm{Calcular\:la\:expresion\:entre\:parentesis}\:\left[7-\left(1-4\right)\right]\::\quad 10\\\\=3\cdot \:10-12/\left(-5+7-8+10\right)\left(-3-5-4\right)\\\\\mathrm{Calcular\:la\:expresion\:entre\:parentesis}\:\left(-5+7-8+10\right)\::\quad 4\\\\=3\cdot \:10-12/4\left(-3-5-4\right)\\\\\mathrm{Calcular\:la\:expresion\:entre\:parentesis}\:\left(-3-5-4\right)\::\quad -12\\\\=30-12/4\left(-12\right)$

$=30+\frac{1}{4}\\\\=\frac{121}{4}$
