To simplify the system of equations from the image, let's first break down both equations and simplify step by step.

Given equations:

1. $\frac{20 - V_1}{10} = \frac{V_1}{-j2.5} + \frac{V_1 - V_2}{j4}$
2. $(1 + j1.5)V_1 + j2.5V_2 = 20$

Steps for Simplification of Equation 1:

$\frac{20 - V_1}{10} = \frac{V_1}{-j2.5} + \frac{V_1 - V_2}{j4}$

1. Multiply through by 10 to eliminate the denominator on the left-hand side: $20 - V_1 = \frac{10V_1}{-j2.5} + \frac{10(V_1 - V_2)}{j4}$

2. Simplify the terms involving $j$:

   • $\frac{10V_1}{-j2.5} = -\frac{4V_1}{j} = 4jV_1$
   • $\frac{10(V_1 - V_2)}{j4} = \frac{2.5(V_1 - V_2)}{j} = -2.5j(V_1 - V_2)$

So, the equation becomes: $20 - V_1 = 4jV_1 - 2.5j(V_1 - V_2)$

Simplification of Equation 2:

$(1 + j1.5)V_1 + j2.5V_2 = 20$

This equation is already in its simplest form, but we can expand it if needed.

Follow-up Questions:

1. Would you like help solving for $V_1$ and $V_2$ from these simplified equations?
2. Should we focus on solving the real and imaginary components separately?
3. Would you prefer a detailed explanation of how complex numbers affect the simplification process?
4. Do you need a breakdown of how I simplified the terms involving $j$?
5. Should I rearrange the second equation for easier substitution?

Tip:

When dealing with complex numbers in equations, it's often helpful to separate real and imaginary parts early to simplify the solving process.
