Question

Chris is six years older than his sister Kennedy. The sum of their ages is 38. Write an equation to find Chris and Kennedy's ages. Make certain that you indicate what the variable represents.

Answer 1

Answer:16 , 22

Explanation:

Given

Chris is six-year older than his sister

The sum of their ages is 38

Suppose the age of Chris sister is x

So Chris age is
`x+6`

the sum is

`\Rightarrow x+x+6=38\\\Rightarrow 2x+6=38\\\Rightarrow 2x=32\\\Rightarrow x=16`

Chris age
`16+6=22\ \text{years}`

Chris sister Kennedy's age
`16\ \text{years}`
