Answer:

18

Step-by-step explanation:

David=x

Michelle=x-2

Karen=x-2+6=x+4

sum of ages=62

x+x-2+x+4=62

3x=60

x=20

age of Michelle=20-2=18

Answer: Michelle is 18 years old

Step-by-step explanation:

Let Karen = 6+M

Michelle= M

David = M+2

Sum of their ages is 62

Therefore, (6+M)+M+(M+2)=62

Adding them together,

3M+8=62

3M=62-8

3M=54

Dividing both sides by 3,

M=18

Since M= Michelle, She is 18 years old
