Question

cuánto es -4[(5×6)+3(x-1)]+7=-2[6(x-1)+9]. ???​

Answer 1

Respuesta:

$4\left(\left(5\times \:6\right)+3\left(x-1\right)\right)+7=-2\left(6\left(x-1\right)+9\right)\quad :\quad x=-\frac{121}{24}$

Explicación paso a paso:

$4\left(5\times \:6+3\left(x-1\right)\right)+7=-2\left(6\left(x-1\right)+9\right)$

$\left(30+3\left(x-1\right)\right)+7=-2\left(6\left(x-1\right)+9\right)$

$12x+115=-12x-6$

$12x+115-115=-12x-6-115$

$12x=-12x-121$

$12x+12x=-12x-121+12x$

$\frac{24x}{24}=\frac{-121}{24}$

$x=-\frac{121}{24}$
