Answer:

Kim is younger than 5 years. Kim could 1, 2, 3 or 4 years old.

Step-by-step explanation:

Let Kim's age be z.

From the question, Josh's age can be as represented below;


Josh^(\prime)s\text{ age =}4z+6

We're also told that the sum of their ages is less than 31, we can express this as per below;


z+(4z+6)<31

So let's go ahead and find Kim's age, z;


\begin{gathered} 5z<31-6 \\ z<(25)/(5) \\ z<5 \end{gathered}

So Kim is younger than 5 years. Kim could 1, 2, 3 0r 4 years old.
