x%2F%28-4%29+%3E+0
I'll try an approach where you don't have to multiply by 0
Add %28-4%29%2F%28-4%29 to both sides
x%2F%28-4%29+%2B+%28-4%29%2F%28-4%29+=+%28-4%29%2F%28-4%29
%28x-4%29%2F%28-4%29+=+%28-4%29%2F%28-4%29
Multiply both sides by -4
When you do this, you have to turn the > sign around
x-4+%3C+16%2F%28-4%29
x-4+%3C+-4
add 4 to both sides
x+%3C+0
(or, x is negative)
This makes sense, because a (-) /(-) is always > 0
