–2(3x +2) = 5(x – 4)

Answer 1

Respuesta:

$-2\left(3x+2\right)=5\left(x-4\right)\\\\-2\left(3x+2\right)\\\\\mathrm{Poner\:los\:parentesis\:utilizando}:\quad \:a\left(b+c\right)=ab+ac\\a=-2,\:b=3x,\:c=2\\\\=-2\cdot \:3x+\left(-2\right)\cdot \:2\\\\=-2\cdot \:3x-2\cdot \:2\\\\-6x-4$

$\\\\\\5\left(x-4\right)\\\\\mathrm{Poner\:los\:parentesis\:utilizando}:\quad \:a\left(b-c\right)=ab-ac\\\\a=5,\:b=x,\:c=4\\\\=5x-5\cdot \:4\\\\=5x-20$

$-6x-4=5x-20\\\\-6x-4+4=5x-20+4\\\\-6x=5x-16\\\\-6x-5x=5x-16-5x\\\\-11x=-16\\\\x=\frac{-16}{-11} \\\\x=\frac{16}{11}$
