Did you leave something out of the statement of the problem? "... more than four times as old..." doesn't give enough information to get a single answer.

n Nene
t sTella
system%28n%2Bt=47%2Cn%2B7%3E4%28t%2B7%29%29

n%2B7%3E4t%2B28
n%3E4t%2B21

Try starting with t=0, so then n%3E21. Does this make sense?
If so, then n%2B21=47;
n=26
Maybe.

Nene and Stella are always 26 years apart.
Nene may be 26 years of age when Stella (t) was born.
