                                                             l         now add the 8 for this side and get 21
Alaine is 13 and Tyler is 21 :)

Tyler ... x years
Elaine ... x years - 8 years
The sum of their ages is 34 ... x + (x - 8) = 34

The equation is x + (x - 8) = 34.

If you want to solve the equation, you can calculate it like this:
x + (x - 8) = 34
x + x - 8 = 34
2 * x = 34 + 8
2 * x = 42    /2
x = 42 / 2
x = 21

Tyler is 21 years old and Elaine is 13 years old (21 - 8).
