Find the value of x:

(35-207)= x mod 11

Can someone show the steps for this answer? I just don't know what to do after I get -172.

So x is the remainder when you divide -172 by 11, ie. it is the solution of the equation:

where n is an integer and x is defined to be .

I get n = -16 as giving x in the required interval, so
