Joe is twice Sara’s age . Kyle isn’t 2 years older that Sara’s age . If the sum of their ages is 42 , how old are Joe, Sara, and Kyle

Question

I don’t under this question so I need help understanding it ASAP cause it’s my homewor and it’s due tomorrow 

Answer 1

J = 2S

 

K = S + 2

 

J + K + S = 42

 

2S + S + 2 + S = 42

 

4S + 2 = 42

 

4S = 40

 

S = 10

 

Joe is 20

Sara is 10

Kyle is 12

 

You said Kyle ISN'T 2 years older than Sara. But in fact, he is.
