The image contains a system of linear equations involving variables \( I_1 \), \( I_2 \), and \( I \). Here is the system as extracted from the image:

\[
8 = 550 \cdot I_1 + 330 \cdot (I_1 - I_2)
\]
\[
880 \cdot I_1 - 330 \cdot I_2 = 8
\]
\[
0 = 330 \cdot (I_2 - I_1) + 600 \cdot I
\]
\[
930 \cdot I_2 - 330 \cdot I_1 = 0
\]

We have four equations, though the second and fourth equations seem to be derived from the first and third respectively. This appears to be a system of two independent equations involving \( I_1 \), \( I_2 \), and \( I \).

I'll solve the system step-by-step to find \( I_1 \), \( I_2 \), and \( I \).

Let me proceed with solving these equations.from sympy import symbols, Eq, solve

# Define the variables
I1, I2, I = symbols('I1 I2 I')

# Define the system of equations from the image
eq1 = Eq(880 * I1 - 330 * I2, 8)
eq2 = Eq(930 * I2 - 330 * I1, 0)
eq3 = Eq(330 * (I2 - I1) + 600 * I, 0)

# Solve the system of equations
solution = solve([eq1, eq2, eq3], (I1, I2, I))
solutionThe solution to the system of equations is:

\[
I_1 = \frac{124}{11825} \approx 0.0105
\]
\[
I_2 = \frac{4}{1075} \approx 0.00372
\]
\[
I = \frac{4}{1075} \approx 0.00372
\]
