Let's solve this step by step using the given equations and find the value of the
burger.
We are given several equations with characters from *SpongeBob SquarePants*:
---
Step 1: Assign variables
Let’s assign variables to each character:
- Let
S = SpongeBob
- Let
B = Burger
- Let
P = Pineapple house (SpongeBob’s house)
- Let
P = Plankton (the green, one-eyed villain)
Wait — we need different letters. Let's use:
-
S = SpongeBob
-
B = Burger
-
H = House (Pineapple)
-
P = Plankton
---
Now let’s write out the equations.
---
Equation 1:
$$
S + S - B = 7
\Rightarrow 2S - B = 7 \quad \text{(Equation A)}
$$
---
Equation 2:
$$
S - P = 1 \quad \text{(Equation B)}
\Rightarrow S = P + 1
$$
---
Equation 3:
$$
H = 7 - 3 + 1 = 5 \quad \text{(Equation C)}
\Rightarrow H = 5
$$
So the
Pineapple house (H) is equal to
5.
---
Equation 4:
$$
P + H = 9 \quad \text{(Equation D)}
$$
We already know $ H = 5 $, so plug in:
$$
P + 5 = 9 \Rightarrow P = 4
$$
Now from Equation B: $ S = P + 1 = 4 + 1 = 5 $
So:
- $ P = 4 $
- $ S = 5 $
- $ H = 5 $
Now go back to Equation A:
$$
2S - B = 7
\Rightarrow 2(5) - B = 7
\Rightarrow 10 - B = 7
\Rightarrow B = 10 - 7 = 3
$$
---
✔ Final Answer:
$$
\boxed{3}
$$
The
burger equals
3.

Summary of values:
- SpongeBob (S) = 5
- Plankton (P) = 4
- House (H) = 5
- Burger (B) =
3
✔ All equations check out:
- $ 5 + 5 - 3 = 7 $ → ✔️
- $ 5 - 4 = 1 $ → ✔️
- $ H = 7 - 3 + 1 = 5 $ → ✔️
- $ 4 + 5 = 9 $ → ✔️
---
🍔 Answer: The burger equals 3.
