Question 1174662

Tom is 8 years older than Kristina. In 5 years the sum of their ages will be 64. How old is Tom now?
<pre>Let Tom's age be T
Then Kristina's is: T - 8
We then get: T + T - 8 + 2(5) = 64
2T - 8 + 10 = 64
2T = 62
Tom, or {{{highlight_green(matrix(1,6, T, "is:", 62/2, "=", 31, years-old))}}}
