n) 2.(x - 2) + 5.(2-x)+6.(x + 1)=0 R:-4​

Answer 1

Explicação passo-a-passo:

2x - 4 + 10 - 5x + 6x + 6 = 0

2x - 5x + 6x = 4 - 10 -6

3x = -12

x = -12/3

x= -4

Answer 2

Olá,

$2.(x - 2) + 5.(2-x)+6.(x + 1)=0$

$2x - 4 + 10 - 5x + 6x + 6 = 0$

$2x - 5x + 6x = 4 - 10 - 6$

$- 3x + 6x = - 6 - 6$

$3x = - 12$

$x = \frac{ - 12}{3}$

$x = - 4$
