Answer:
Any number greater than 49.
Step-by-step explanation:
Since 7>0 then multiplying both sides of x>7 by 7 will not effect the direction of the inequality.
If x>7, then 7x>7(7) or 7x>49 after simplifying.
Substituting y for 7 since y=7 gives yx>49.
By commutative property of multiplication we have xy>49.
So any number greater than 49.
