Answer:

#7xx(-7)=color(blue)(-49)#

Explanation:

One way to think about this is to consider positive numbers as money I actually have and negative numbers as amounts I owe to other people.
Then if I owed #$7# to #7# people
then I would have #7xx(-7)=-49#; that is I would owe a total of #$49# dollars
