Answer 1

Kim's age is twice of that of her sister. We'll let k2 = Kim and k = Kim's sister.

So, k2. When you add Kim's age to her sister age you get 36.

Because Kim is twice the age of her sister k2. And because it said 'add' then we put a + sign. k2 + s = 36. Now let's solve it. 

k2 + k = 36 < Given

3k = 36 < Combine like terms

k = 12 < Divide both sides by 3

We know Kim's sister is 12 y/o but what about Kim herself? Earlier we assigned Kim to k2. Substitute 12 for k and you get 12(2) = 24

Kim's sister is 12 y/o and Kim is 24 y/o

Answer 2

Answer:

Kim's age is 16 and her sister's age is 8.

Step-by-step explanation:

(a) If Kim's age is 2x then  her sisters age is x years.

Also x + 2x = 24.

The equation is 3x = 24.

b) Solving 3x = 24 gives x = 8  and 2x = 16.

So Kim's age is 16 and her sister's age is 8.
