Question

Jack split 25 jellybeans between his brother and himself so that his brother has one more than twice the number Jack has. How many jellybeans does each have?

Answer 1

Jack has 8
And his brother has 17

Answer 2

Jack has 8 and his brother has 17

Explanation:

j = # jack has

b = # brother has

j + b = 25

b = 1 + 2j (brother has one more than twice the amount jack has)

j + 1 + 2j = 25

3j = 24

j = 8

b = 25-8 or 17
