You're pretty good if you can do it without algebra!
It is given that the same number of both the jeans
and shirts were sold on both days
Let = number of jeans sold on both days
Let = number of shirts sold on both days
given:
(1)
(2)
Now I will multiply both sides of (1) by
and both sides of (2) by . Then I will
subtract (1) from (2)
(2)
(1)

Now plug this result back into either (1) or (2)
(2)

9 jeans and 12 shirts were sold each day
You can plug these numbers back into original quations
to check
