George is 78 years old.

We know that #400-2x=244#, where #x# is George's age. We can solve for #x# by adding #2x# to both sides and subtracting #244# from both sides.

#400-2x+2x-244=244+2x-244#

The result is: #156=2x#.

We can now divide both sides by #2# to get the answer.

#156/2=2x/2#

#x=78#

George is 78 years old.
