Solve the animal math puzzle: What is the value of the final equation?

Let’s solve this step by step.

We are given 3 equations with cartoon animals, and we need to find the value of the final expression:

> Horse × Duck – Cow = ?

---

Step 1: Assign variables

Let:
- Duck = D
- Horse = H
- Cow = C

---

Step 2: Write the equations from the image

Equation 1:
D + D + D = 30
→ 3D = 30
→ D = 10

---

Equation 2:
D + H + H = 20
→ 10 + 2H = 20
→ 2H = 10
→ H = 5

---

Equation 3:
H + C + C = 9
→ 5 + 2C = 9
→ 2C = 4
→ C = 2

---

Step 3: Plug into the final expression

Final expression:
H × D – C = ?

Substitute values:
= 5 × 10 – 2
= 50 – 2
= 48

---

✔ Final Answer: 48

---

Summary:

- Duck = 10
- Horse = 5
- Cow = 2
- So, Horse × Duck – Cow = 5 × 10 – 2 = 48
