Answer:5
Step-by-step explanation:
Given
Rachel sold twice as many books on tuesday as she did on monday
and on Wednesday she sold 6 fewer books than she did on tuesday during three days .
Let books sold on Monday is x
therefore on tuesday it is 2x
on wednesday it is 2x-6
And Rachel sold a total of 19 books '
therefore
x+2x+2x-6=19
5x=25
x=5
Therefore she sold 5 books on Monday
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.
