Question

es el valor de la ecuación dos[3x(2 menos 4)+2x- 5(x+1]=-28​

Answer 1

Hola! :3

Resolvemos:

2[3x(2 - 4) + 2x - 5(x + 1)] = 28

3x(-2) + 2x - 5(x + 1) = 28/2

-6x + 2x - 5x - 5 = 14

(-6 + 2 -5)x - 5 = 14

-9x - 5 = 14

-5 - 14 = +9x

-19 = 9x

-19/9 = x

Espero haberte ayudado :D

Answer 2

Respuesta:

x = 1

Explicación paso a paso:

2[3x(2 - 4) + 2x - 5(x + 1)] = -28

2[3x(-2) + 2x - 5(x + 1)] = -28

2[-6x + 2x - 5x - 5] = -28

2[-9x - 5] = -28

-9x - 5 = - 28 / 2

-9x - 5 = -14

-9x = -14 + 5

-9x = - 9

x = -9 / -9

x = 1
