x + 3 < n - 1
How do you turn the above equation into x+n<2n-4 ???
I did the following.
x-n < -4
-1(x-n) > (-4)-1
n-x > 4
Am I missing something extremely obvious? This seems too easy to get stumped on.

subtract 3 both sides
x < n-4
add n both sides
x+n < n+n -4
=> x+n < 2n -4

you are given inequality not equation, x + 3 < n - 1 could be rewritten as x < n - 4 OR x + n < n+n - 4 which is equivalent to x + n < 2n - 4
