Question

resolver x+7(8-9x)-8=5+6x-8

Answer 1

x + 7 (8 - 9x) - 8 = 5 + 6x - 8

x + 56 - 63x - 8 = 5 + 6x - 8

x - 63x - 6x = 5 - 8 + 8 - 56

-68x = -51 = simplificamos la diecisieteava

-68x/-51

x = 4/3 

Respuesta : 

x = 4/3

Answer 2

Resolver.

x + 7(8 - 9x) - 8 = 5 + 6x - 8
x + 56 - 63x - 8 = 5 + 6x - 8
- 62x + 48 = 6x - 3
48 + 3 = 6x + 62x
51 = 68x
51/68 = x  Simplificas sacas 17ava
(51/17)/(68/17) = x
3/4 = x
x =3/4

Respuesta.
El valor de x es 3/4
