please solve this thanks​

Answer 1

Answer:

5x + 2x = 1421

7x = 1421

7x/7 = 1421/7

x = 203

Fiction Books

5x = 5 (203) = 1015

There are 1015 fiction books.

Non-Fiction Books

2x = 2 (203) = 406

There are 406 non-fiction books.

To know how many more fiction than non fiction books there are in the library, we need to subtract.

1015 - 406 = 609

Final Answer:

There are 609 more fiction books than non fiction books in the library.

Checking:

5x + 2x = 1421

1015 + 406 = 1421

1421 = 1421 ✔

Cross multiply.

5:2 = 1015:406

2 × 1015 = 5 × 406

2030 = 2030 ✔
