Question

Hola, ¿Alguien sabe esto?... 2.(x-1)+15=1

Answer 1

La ecuación que tienes es:
2 (x - 1) + 15 = 1
2x - 2 + 15 = 1
2x + 13 = 1
2x = 1 - 13
2x = - 12
x = - 12/2
x = - 6

Respuesta
x = - 6

Answer 2

2 . (x-1) + 15 = 1
2x - 2 + 15 = 1 (Aplicamos distributiva)
2x - 2 = 1 - 15
2x - 2= -14
2x = -14 + 2
2x = -12
x =-12 :2
x= - 6

Comprobamos:
2. (x-1) + 15 =
2 . (-6 - 1) + 15 =
-12 -2 + 15 =
-14 + 15 =
1
