Answer:

-2

Step-by-step explanation:

let the number be 'x'

then the equation can be:

12 - 2x = 8(x+4)

12 - 2x = (8*x) + (8*4)

12 - 2x = 8x + 32

(bring variables to one side and constant terms to another side)

-2x - 8x = 32 - 12

so,

-10x = 20

therefore, x = 20/-10 = -2

so, the number is -2.
