Answer:
the cost of each book = $24
Step-by-step explanation:
(if all the books have the same price)
Let x be the price of one book
“She had $157 and After buying 6 books ,she was left with 13$“ means
“157 = 6x + 13”
now we have an equation to solve :
157 = 6x + 13
⇔ 157 - 13 = 6x
⇔ 144 = 6x
⇔ 24 = x

Answer:
AB + BC = AC
BC = AC - AB
5x + 6 = 37 - (2 x + 3) = 37 -2 x - 3 = 34 - 2 x
7 x = 34 - 6 = 28
x = 4
BC = 5 x + 6 = 5 * 4 + 6 = 26
Check:
AB = 2 x + 3 = 2 * 4 + 3 = 11
AB + BC = 26 + 11 = 37
21x-9+6y
combining terms: 4x+17x=21x
