Instructions for solving lesson 2 page 48 textbook practice 5 practice

My age and my age combined 36. I’m 8 years younger than my sister. How old are you, how old are you?

Solution method:
* Comment:
– The problem says:
+ Total number of sisters and younger ages: 36
+ I’m younger than you: 8 years old
– Required problem: Find her age; your age.
* Solution:
– Find your age by taking the total number of ages of you and sister – the difference (the number of years you are younger than your sister), and divide by 2.
– Find your age by taking the number of years of my younger brother + the mark (the number of years older than each other).

My age is: (36 – 8): 2 = 14 (years)
My age is: 14 + 8 = 22 (years)
Answer: I’m 22 years old and I’m 14 years old.
