Answer 1

m + t + w = 19
t = 2m
w = 2m - 6

now we sub
m + (2m) + (2m - 6) = 19...combine like terms
5m - 6 = 19
5m = 19 + 6
5m = 25
m = 25/5
m = 5 <== she sold 5 books on Monday

t = 2m......t = 2(5)...t = 10 <== she sold 10 books on Tuesday
w = 2m - 6....w = 2(5) - 6....w = 10 - 6...w = 4 <== she sold 4 books on Wednesday.
