HEY GUYS I NEED THIS ANSWER NOW

Answer 1

Elliot has 7 non fiction books and 19 fiction books

Answer 2

Let

x-------> the number of fiction books

y-------> the number of nonfiction books.

we know that

$x+y=26$ -----> equation $1$

$x=y+12$

$x-y=12$ -----> equation $2$

Add equation $1$ and equation $2$

$x+y=26\\x-y=12\\ ------\\ 2x=38\\ x=38/2\\x=19\ fiction\ books$

find the value of y

$x+y=26$

$19+y=26$

$y=26-19=7\ nonfiction\ books$

therefore

the answer is

Part a)  the number of fiction books is $19\ fiction\ books$

Part b)  the number of nonfiction books is $7\ nonfiction\ books$
