Answer 2

Hola! :)

Resolvemos:

x + (5x + 2) = 7 - 3 (5 - 4x)

x + 5x + 2 = 7 - 3(5 - 4x)

6x + 2 = 7 - 3(5 - 4x)

6x + 2 = 7 - 15 + 12x

6x + 2 = 12x - 8

2 = 12x - 8 - 6x

2 = 6x - 8

2 + 8 = 6x

10 = 6x

10/6 = x

x = 5/3 ⇒Respuesta

Comprobación:

x + (5x + 2) = 7 - 3(5 - 4x)

5/3 + 5 x 5/3 + 2 = 7 - 3(5 - 4 x 5/3)

5/3 + 5 x 5/3 + 2 = 7 - 3(5 - (4 x 5)/3)

5/3 + 5 x 5/3 + 2 = 7 - 3(5 - 20/3)

5/3 + 5 x 5/3 + 2 = 7 - 3 x - 5/3

5/3 + (5 x 5)/3 + 2 = 7 - 3 x - 5/3

5/3 + 25/3 + 2 = 7 - 3 x - 5/3

5/3 + 25/3 + 2 = 7 - (- 5)

36/3 = 7 - (- 5)

12 = 7 - (- 5)

12 = 7 + 5

12 = 12 ✔️
