Answer:

a = 6

Step-by-step explanation:

7a-17 = 4a +1 ; Subtract 4a from both sides

3a - 17 = 1 ; Add 17 to both sides

3a = 18 ; Divide both sides by 3

a = 6

Sergio [31]

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 $7\ nonfiction\ books$
