Question

x+2/x-4  Minus 1   greater than or equal to 0

Answer 1

(x+2)/(x-4) -1 > 0

x+2 = x-4, no real solution, just surreal solutions of +/- infinity

but that's just the = part of the original problem

the > part has real solutions

all real numbers

any x+2 is > x-4 for any real number x

in interval notation (-infinity, +infinity)

in set notation {x|x=any real number}

or x is an element of the set of real numbers, use a script R
