Noah is 8years older than Emma . In 2years the sum of their ages will be 72 . How old is Noah now 
<pre>Let Noah's age be N
Then Emma's is N - 8
If the sum of their ages will be 72 in 2 years' time, then the sum of their ages is: 72 - 2(2) = 68
We now get: N + N - 8 = 68
2N = 76
N, or Noah is: {{{highlight_green(matrix(1,4, 76/2, "=", 38, years-old))}}}
