Question

¿cuanto vale x?


(x + 30) + (x + 25) = 7x


24x - 30x - 6 + 12x = 81 -9x - 54


3x - 2 + 3 - 6x = 2- 2x + 2


2x + 2 (x + 1) = 3 (x + 1)

Answer 1

Respuesta:

x + x - 7x = - 30 - 25

- 5x = - 55

x = - 55/ - 5

x = 11

24x - 30x + 12x + 9x = 81 - 54 + 6

15x = 33

x = 33 / 15

x  = 2.2

3x - 6x + 2x = 2 + 2 + 2 - 3

x = = - 3

2x + 2x - 3x = 3- 2

x = 1
