### Circuit Analysis: Calculation of Current Through Point P

#### Problem Statement:
A circuit consisting of three ideal batteries with voltages \( \mathcal{E}_1 \), \( \mathcal{E}_2 \), and \( \mathcal{E}_3 \), and three ideal resistors with resistances \( R_1 \), \( R_2 \), and \( R_3 \), is shown in the figure.

**Task:** Calculate the current \( I_P \) through point P. Let the sign of the current correspond to its direction, with "up" being positive.

#### Given Data:
- Voltages:
- \( \mathcal{E}_1 = 31.0 \, \text{V} \)
- \( \mathcal{E}_2 = 12.0 \, \text{V} \)
- \( \mathcal{E}_3 = 30.0 \, \text{V} \)

- Resistances:
- \( R_1 = 2.40 \, \text{k}\Omega \)
- \( R_2 = 16.0 \, \text{k}\Omega \)
- \( R_3 = 3.75 \, \text{k}\Omega \)

*Note: 1 kΩ = 1000 Ω*

#### Diagram Explanation:
In the circuit diagram:
- \( \mathcal{E}_1 \) is connected in series with the combination of \( R_1 \) and \( R_2 \).
- \( \mathcal{E}_2 \) is connected at a point between \( R_1 \) and \( R_2 \).
- \( \mathcal{E}_3 \) is connected in a separate branch with \( R_3 \).
- The point P is where \( R_1 \) is connected to the positive terminal of the battery \( \mathcal{E}_1 \) and the rest of the circuit.

To solve for \( I_P \), utilize Kirchhoff's circuit laws which state that the sum of all voltages around any closed loop in a circuit is zero (Kirchhoff's Voltage Law).

Use the known values and the circuit diagram to form the necessary equations and solve for current \( I_P \).

#### Calculation:
To complete this section, apply the principles and steps from Kirchhoff's rules and ohm's law. The
