You age now is 15 years old.

We will let #a# be your age now.

Your age 6 years ago would can then be expressed as #a - 6#,

Twice your age six years ago can be expressed as #2(a - 6)# or #2a - 12)#

Therefore you age us:
#a = (2a - 12) - 3#

#a = 2a - 15#

#a - a + 15 = 2a - a - 15 + 15#

#a = 15#
