Answer
$\gt$
Work Step by Step
RECALL:
The Addition Property of Inequality states that for real numbers $a$, $b$, and $c$,
If $a \gt b$, then $a+(-c) \gt b+(-c)$
Thus. if $x \gt 6$, then, adding $-6$ to each side of the inequality gives:
$x + (-6) \gt 6+(-6)
\\x-6 \gt 0$
Therefore, the missing inequality symbol is $\gt$.
