system%28n=e%2B8%2C%28n%2B2%29%2B%28e%2B2%29=72%29

n%2Be=68
e=68-n


How Old is Noah?
n=%2868-n%29%2B8
n=-n%2B68%2B8
2n=68%2B8
n=34%2B4
highlight%28n=38%29

Noah is 8years older than Emma . In 2years the sum of their ages will be 72 . How old is Noah now 
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%28matrix%281%2C4%2C+76%2F2%2C+%22=%22%2C+38%2C+years-old%29%29
