:
you want to write an equation with one unknown here
Let s = days in S.A.
then
(7-s) = days in Dallas
:
275s + 400(7-s) = 2300
:
275s + 2800 - 400s = 2300
275s - 400s = 2300 - 2800
-125s = -500
s =
s = 4 days in S.A. and obviously, Dallas 3 days

You can check solution by finding the total for each city.
