Question

Resolver: (x – 5) + (3x + 7) = x – (2 – 3x)

Answer 1

 (x – 5) + (3x + 7) = x – (2 – 3x)
x-5+3x+7=x-2+3x
4x+2=4x-2
4x-4x=-2-2
0=-4

x no pertenece....,.

Answer 2

(x – 5) + (3x + 7) = x – (2 – 3x)
4x + 2 = x - (2x -3x)
*agregamos "-2" ambos lados
4x + 2 - 2 = 4x - 2 - 2
4x = 4x - 4
*agregamos "-4x" ambos lados
4x - 4x = 4x - 4 - 4x
0 = - 4

∴ Es divergente.
