#r=-39#

Subtract #6# from both sides.

#0=-9abs(r+39)#

Now the only way this express could be true is if the stuff inside the absolute value is equal to zero.

#abs(r+39)=0#

Because #abs(0)=0#, we can go ahead and set the inside equal to zero.

#r+39=0#

Subtract #39# from both sides.

ANSWER: #r=-39#
