Question 1145242

john is five years older than will. twice johns age in two years is same as four times will's age one year ago. how old is john now?
<pre>Let John's age be J
Then Will's is: J - 5
Based on what's given we get: 2(J + 2) = 4(J - 5 - 1)
2J + 4 = 4(J - 6)
2J + 4 = 4J - 24
4 + 24 = 4J - 2J
28 = 2J
J, or John is: {{{highlight_green(matrix(1,4, 28/2, "=", 14, years-old))}}}
