Question

Which equation could be used to solve the question below?

Tirza has b books. Her mom has 37 books and her sister has 26 books. They have 85 books in all. How many books does Tirza have?
b - 37 + 26 = 85
b + 37 - 26 = 85
b + 37 + 26 = 85
b - 37 - 26 = 85

Answer 1

C) b+37+26=85

Answer 2

well :) We know this
Tirza + mom + sister = 85 right?
Because when we add the amount of books that all three of them have, they have 85 in total.
Since Tirza = b , mom = 37 and sister =26 and total = 85.
We get:
b + 37 + 26 = 85
