The answer is 5 books.
m - the number of books sold on Monday
t - the number of books sold on Tuesday
w - the number of books sold on Wednesday
<span>On Tuesday, she sold twice as many books as she did on Monday: t = 2m
</span><span>On Wednesday, she sold 6 fewer books than she did on Tuesday: w = t - 6
</span><span>During the three days Rachel sold 19 books: m + t + w = 19
</span>t = 2m
w = t - 6 = 2m - 6
m + t + w = 19
______
Substitute t and w in the third equation:
m + 2m + 2m - 6 = 19
5m - 6 = 19
5m = 19 + 6
5m = 25
m = 25 : 5
m = 5
