**What was the question?**

Let's first rewrite all equations and number them

1. A - B = B

```
2. B * C = A
3. D : B = E
4. C * C = E
5. C + E = A
```

For which numbers stand A, B, C, D and E?

From 1, A = 2B. Putting this in 2 gives,

C = 2.

Putting C = 2 in 4 gives, E = 4.

So from 5, A = C + E = 2 + 4 = 6.

Equation 2 gives, B = A/C = 6/2 = 3.

And equation 3 gives D = B * E = 3 * 4 = 12.

Conclusion :

**A = 6**,**B = 3**,**C = 2**,**D = 12**and**E = 4**.
