I haven't done math in years, I have no idea what I'm doing wrong

this is one of many problems I'm stuck on:

-6 (x +1) + 4 = 16

I disribute the negative 6 to the ()

-6 (-11x) = 66x

66x=12

x= 12/66

Then I don't do that I get:

-6(2x)+4-4=16-4

-12x=12

x=-1

I've been stuck on this one for hours, I went through the tutorials and everything and I still do not understand.
