Answer:

Equation= 2x + x = 18.

Answer = 6.

Step-by-step explanation:

Let the no. of books David has be x.

No. of Books Maria has = 2x

Equation = 2x + x = 18

David's books :

= 2x + x = 18

= 3x = 18

= x = 18÷3

= x = 6

Therefore, No. of books David has :

= x

= 6 Books.

Therefore, No. of books Maria has :

= 2x (2×6)

= 12 Books.
