Luke is 4 years younger then Zoe. Mischa is half Luke's age. Let \( z \) be Zoe's age.

If we let Zoe's age be \( z \), then we can express Luke's age as \( z - 4 \) (since Luke is 4 years younger than Zoe). Now, since Mischa is half of Luke's age, we can find Mischa's age as follows: \( \frac{1}{2}(z - 4) \). This gives us a great way to represent everyone's ages in relation to Zoe, making it easy to solve any related problem or set up equations based on these relationships! Understanding how to set up relationships like this can help you in various situations, such as planning events with friends or calculating ages for fun riddles! It’s all about seeing the connections and using them to find solutions, and remember, small errors in age relationships can lead to larger misunderstandings. Double-check your equations whenever you're solving age problems to avoid mix-ups!
