n=-11

If 4 less than n is -15, then the following must be true.

#n-4=-15#

To solve this equation, we need to add four to both sides.

#n-4+4=-15+4#

This is simplified to the following.

#n=-11#

#n=-11#

The sentence means
#n-4=-15#

#n-4+4=-15+4#
#n-4+4=-11#

#n-cancel4+cancel4=-11#

#n=-11#

God bless....I hope the explanation is useful.
