Question 342237
Tom is 3 years older than kim. joe is twice as old as tom. their combined age is 53. What is the age of joe?


Let Kim's age be K years


Since Tom is 3 years older than kim, then Tom's age is K + 3, and since Joe is twice as old as tom, Joe is 2(K + 3), or (2K + 6) years-old


Since their ages sum to 53, then we can say that: 


K + K + 3 + 2K + 6 = 53


4K = 44


K, or Kim's age is {{{44/4}}} or 11. 


Since Joe is (2K + 6) years-old, then Joe is 2(11) + 6, or {{{highlight_green(28)}}} years-old.
