Elaine is 8 years younger than her brother tyler. the sum of their ages is 34. what are elaine's and tyler's age?

Here, Elaine = Tyler + (-8)

⇒ Elaine + 0 + Tyler + 0 = 34
⇒ Tyler + (-8) + 0 + Tyler + 0 = 34

And, Tyler = [(34 - (0) - (-8)] / 2

Thus, Tyler = 21
And, Elaine = 21 + (-8)
                   =13

∴ Tyler = 21 & Elaine = 13
