⦁kim's age is twice that of her sister. when you add kim's age to her sister's age, you get 24. how old is each sister?
⦁ write an equation that represents the situation. explain any variable used.
⦁ solve the equation from part (a). show your work. state your solution as a complete sentence.

Kim is 16 years old and her sister is 8 years old.

Step-by-step explanation:

We can use equations to represent this scenario.

Let Kim's age be 'k' and her sister's age be 's'.

Thus, k=2s (since Kim's age is double of her sister)

and k+s=24 (their ages add to 24 (from question)

Substituting the first equation:

2s+s=24

3s=24

s=8

Therefore, Kim's sister is 8 years old.

Now substitute this value into the second equation:

k+8=24

k=16

Therefore, Kim is 16 years old.
