Question
### Application of Kirchhoff's Rules

An application of Kirchhoff's Rules to the circuit shown results in the following system of equations. Find the currents \( I_1 \), \( I_2 \), \( I_3 \):

\[
\begin{cases}
I_2 = I_1 + I_3 \\
5 - 4I_1 - 5I_2 = 0 \\
10 - 5I_2 - 7I_3 = 0
\end{cases}
\]

**Diagram Explanation:**
The diagram depicts a circuit comprising the following components:
1. Three resistors with resistances of 7Ω, 5Ω, and 4Ω.
2. Two voltage sources of 10V and 5V.
3. Three currents \( I_1 \), \( I_2 \), and \( I_3 \), flowing in different parts of the circuit. \( I_1 \) flows through the 5Ω and 4Ω resistors, \( I_2 \) passes through the 7Ω and 5Ω resistors, and \( I_3 \) flows through the 7Ω resistor.

The direction of \( I_1 \) is shown as flowing to the right, \( I_2 \) is flowing upwards, and \( I_3 \) is flowing to the left.

---

### Question:
Select the correct choice below and fill in any answer boxes in your choice.

**Options:**
- **A.** The currents are \( I_1 = \_\_\_ \), \( I_2 = \_\_\_ \), and \( I_3 = \_\_\_ \). (Type integers or fractions.)
- **B.** There are infinitely many solutions.
- **C.** There is no solution.
