Question

2x+7-4(3x-4)=-3(x-12)+1

Answer 1

2x+7-12x+16=-3x+36+1

2x-12x+3x=36+1-7-16

-13x=12

Answer 2

Respuesta:

X = -2

Explicación paso a paso:

$2x + 7 - 4(3x - 4) = - 3(x - 12) + 1 \\ 2x + 7 - 12x + 16 = - 3x + 36 + 1 \\ 2x - 12x + 16 + 7 = - 3x + 36 + 1 \\ - 10x + 23 = - 3x + 37 \\ 23 - 37 = - 3x + 10x \\ - 14 = 7x \\ \frac{ - 14}{7} = x \\ - 2 = x$
