16 years

Step-by-step explanation:

Hello,

Let's note a Annet's age and b her sister's age.

Annet is 6 years younger than her sister, so we can write:

Their total age is 38 years, so we can write:

It comes

b - 6 + b = 38

<=> 2b - 6 = 38

add 6 to both parts of the equation

<=> 2b = 38 + 6 = 44

divide by 2

<=> b = 44/2 = 22

So, Mary's age is 22.

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

22

Step-by-step explanation:

Total age = 38

Mary's age = x

Annet's age = x - 6

So , the equation is :

x + ( x - 6 ) = 38 and when you solve it you'll get the answer x as 22 and then you have to subtract it with 6 so that you can get the answer for Janet's age which is 16 so , 22 + 16 = 38

Hope this helps and pls mark as brainliest :)

a is the correct
