Expression to get the date of Friday of the previous week

This expression works

addDays(utcNow(), dayOfWeek(utcNow()), 'dd-MMM-yyyy')
and adds, 1, 2, 3 etc. days in function of the current weekday.
How can I turn dayOfWeek(utcNow() into  - dayOfWeek(utcNow) -2
so that e.g. on a Monday it substracts 3 and on Tuesday it substracts 4 days to give me last Friday's date?
I expected something like 
addDays(utcNow(),-dayOfWeek(utcNow())-2, 'dd-MMM-yyyy')
would work but apparently I'm missing a point or two. 
Some help is greatly appreciated.

You want to use the sub expression.

 

addDays(utcNow(), sub(-2,dayOfWeek(utcNow())), 'dd-MMM-yyyy')

Indeed, sub() was what I was looking for. Thank you so much for the prompt response!
