Question

How do you do this?
please help if possible!

Answer 1

(a) need to find the number of books, we'll call it "b". then the money (6w) minus the cost of books (17b) equals change left over (w)
6w - 17b = w
6w - w = 17b
5w = 17b
(5/17)w = b

(b) if w = 34
(5/17) *34 = b
10 = b

Answer 2

a) Solution:
Angela bought some books for $17 each.
That means , she bought x books for $17x
Initially, she had $6w.Later she has $w left.

Writing this as a equation,
6w-17x=w
6w-w=17x
5w=17x
x=5w/17➡Ans 1

b) Solution:
If w=34,
↪x=5×34/17
=10➡Ans 2
So , she bought 10 books in this case.
