It is so absurdist . . . that I have no adequate words in my mouth to continue.


My advise to all other tutors is simply ignore this post to avoid stroke.


It is a rare case to meet such idiotic  "problem".


It only confirms my hypothesis that so called "visitors" collect and retrieve their "problems" from trash bins of the Internet.

w, woman
d, daughter

system%28w=4d%2C%28w%2B5%29%5E2-%28d%2B5%29%5E2=120%29

Substitute for w, and ,...
15d%5E2%2B30d=120
.
.
d%5E2%2B2d-8=0
%28d-2%29%28d%2B4%29=0
highlight%28d=2%29 and w=8.


These results are not very typical values, to say the least. Maybe recheck the original problem description.
