Question 119063
GOLIATH IS 12 YEARS OLDER THAN DAVID. IN SIX YEARS, GOLIATH'S AGE WILL BE TWICE OF DAVID'S AGE. HOW OLD IS GOLIATH NOW?
-----------------
NOW DATA:
Let David's age be "x" yrs. old 
Then Goliath is "x+12" yrs. old
--------------------------
Six years from now:
David will be "x+6" yrs. old
Goliath will be "x+18" yrs old
------------------------
EQUATION:
G = 2D
x+18 = 2(x+6)
x+18 = 2x+12
x = 6 (David is 6 yrs old)
x+12= 18 (Goliath is 18 yrs. old)
