Question 53921
Joe lived 1/6 of life as a child and 1/12 as a youth and 1/7 before he married and 5 years before son was born. Son live 1/2 of his life then Joe lived 4 more years. How old was Joe when he died.
:
Just add up fractions & years given, it should add up to the total years of his life
:
Let x = Joe's life-time
:
x = (1/6)x + (1/12)x + (1/7)x + 5 + (1/2x) + 4 
:
A good common denominator would be 84
x = (14/84)x + (7/84)x + (12/84)x + 5 + (42/84) + 4 
:
mult equation by 84:
84x = 14x + 7x + 12x + 420 + 42x + 336
:
84x = 75x + 756
:
You should be able to solve it now
