Answer 2

$Solution, 4\left(2x-5\right)-12x=-4x-20$

$Steps:$

$Simplify, 4\left(2x-5\right)-12x$

$\mathrm{Expand}\:4\left(2x-5\right),\\4\left(2x-5\right),\\\mathrm{\mathrm{Apply\:the\:distributive\:law}:\quad \:a\left(b-c\right)=ab-ac,\:a=4,\:b=2x,\:c=5,\:4\cdot \:2x-4\cdot \:5,}\\\mathrm{Simplify}\:4\cdot \:2x-4\cdot \:5,\\4\cdot \:2x-4\cdot \:5,\\\mathrm{\mathrm{Multiply\:the\:numbers:}\:4\cdot \:2=8,\:8x-4\cdot \:5,}\\\mathrm{\mathrm{Multiply\:the\:numbers:}\:4\cdot \:5=20,\:8x-20}$

$\mathrm{Simplify}\:8x-20-12x,\\\mathrm{\mathrm{Group\:like\:terms},\:8x-12x-20,}\\\mathrm{\mathrm{Add\:similar\:elements:}\:8x-12x=-4x,\:-4x-20}$
