Question

Elaine is 8 years younger than her brother Tyler. The sum of their ages is 34. Define a variable and then write and solve an equation to find Elaine’s and Tyler’s ages.

Answer 1

Answer: Elaine=13 years old Tyler=21 years old

Explanation:

Let x = Elaine's age, so her brother Tyler's age = x+8

Elaine+Tyler=34

x+(x+8)=34

2x+8=34

2x=26

x=13

Elaine=13 years old

Tyler=21 years old
