Answer:
Answer explained below.Step-by-step explanation:
A.
Given that,
Hana age = Y years
Hana's brother is 10 years younger than twice her age.
So, her brother's age = (2Y - 10) years
Also, given, Y = 14
Thus, her brother's age = 2(14) - 10 = 28 - 10
= 18 years
B. Given that,
Hana's neighbor is five years older than half her age find her neighbors age
So, her neighbor's age = (1/2)Y + 5
Putting Y = 14, her neighbor's age = (1/2)14 + 5
= 12 years
