x > 4

Explanation:

Given
color(white)("XXX")-2x+6 < x-6

Add 2x to both sides
color(white)("XXX")6 < 3x-6

Add 6 to both sides
color(white)("XXX")12 < 3x

Divide both sides by 3
color(white)("XXX")4 < x

(This could be inverted to get a more standard form with x on the left as)
color(white)("XXX")x > 4
