Tom spent (in order) a third of his life to date in the united states, a sixth in india, twelve years in egypt, half the remainder of his time in australia, and as long in canda as he spent in india. where did he spend his fortieth birthday?
use an alegbraic equation to solve this problem. explain your answer.
i cant solve for the equation to know how long he lived. when i set them up i get a different country each time. please help!!!grade depends on it!!!

xlifespan
1/3*x+1/6*x+12+y+1/6*x=x
since y is "half the remainder of his time", it means it's equal 1/6*x
solving the equation:
x=72
USA  24 years
India  12 years
Egypt  12 years
So the answer is EGYPT.
