Question

My sister is 2 years older than I am. The sum of our ages is 32. Find our ages.

Answer 1

You are 15 and your sister is 17 

Answer 2

Lets call your age x and your sisters would be x +2
x + x + 2 = 32
combine like terms
2x + 2 = 32
32 - 2 = 2x
32 - 2 = 30
2x = 30 
x = 15

Your age is 15 and your sisters is 17

Hope This Helps You!
