Question

Sonja had m books and Alfonzo had twice as many, the two together having 18 books. How do you solve?​

Answer 1

sonja has 6 books because alfronzo has twice as much which means he has 12 books and that’s because we multipled sonja’s amount of books with 2 and added 12+6 = 18 (the amount of all their books together)

Answer 2

sonja has 6 books

Explanation:

let m = amount of books sonja has

2m+m=18

combine like terms

3m=18

divide

m=6
