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
