d/2 +d/5 + d/3 = 3
(15d + 6d + 10d) / 30 = 3
15d + 6d + 10d = 90
31d = 90
d = 90/31
d = 2 28/31

Step-by-step explanation:
Let x = number of children's books sold,
and let y = the number of adult books sold
The library sells 376 books at its annual used-book sale
so, we get equation as

Children's books cost $4
So, total cost of children book is 4x
adult books cost $7
So, total cost of adult book is 7y
so, we get total cost is 4x+7y
he sale takes in a total of $2119
so, we get equation as

so,
system of equations are
