Question

3(2x + 4) – x + 2 = 3x + 2 urgente

Answer 1

Respuesta:

$x = -6$

Explicación paso a paso:

$3(2x + 4) - x + 2 = 3x + 2\\\\6 x + 12 - x + 2 = 3 x + 2\\\\6 x - x - 3 x = 2 - 2 - 12\\\\2 x = - 12\\\\x = \frac{-12}{2}\\\\x= -6$

Comprobación:

$3 ( 2 ( - 6 ) + 4 ) - (-6 ) + 2 = 3 (-6) + 2\\\\3 ( - 12 + 4 ) + 6 + 2 = - 18 + 2\\\\3 ( -8 ) + 8 = -16\\\\-24 + 8 = - 16 \\\\- 16 = -16$
