Let the man's age be the unknown value x. To get started, imagine a man spending half of his life sleeping and the other eating. The equation to solve that unknown age would be
x%2F2%2Bx%2F2=x just let the man be 100, (100/2+100/2=50+50=100)
Now we're dealing with more fractions in this problem
x%2F9%2Bx%2F12%2Bx%2F3%2B10%2Bx%2F4%2B6=x
28x%2F36%2B16=x
%2828x%2B576%29%2F36=x
-8x=-576Solve for x
x=72
So the man was 72 when he died. Hope this helps.
