Question 1052708
 Freddy is 4 years older than 8 times his grandson's age. The sum of their ages is greater than 67. 
What is the youngest age Freddy's grandson can be?
------------------------ 
F=G*8+4
F+G>67 
now I don't know what to do
Substitute for "F" and solve for "G"
8G + 4 + G > 67
9G > 63
G > 7
----
Ans G = 8 yrs
