Solve the system of equations for x,y,p and q

-0.798p -0.568q -0.254qy + 0.6 + y = 0
-0.502p -0.822q -0.296px + 0.6 + x = 0
-0.798x -0.502y +0.032qx -0.222qy + 0.502 + 0.968q=0
-0.822y -0.568x -0.198px +0.098py +0.568+0.902p=0

We have a system of four equations with four unknowns \(x\), \(y\), \(p\), and \(q\). The system is as follows:

\[
\begin{aligned}
1.\ & -0.798p - 0.568q - 0.254qy + 0.6 + y &= 0 \\
2.\ & -0.502p - 0.822q - 0.296px + 0.6 + x &= 0 \\
3.\ & -0.798x - 0.502y + 0.032qx - 0.222qy + 0.502 + 0.968q &= 0 \\
4.\ & -0.822y - 0.568x - 0.198px + 0.098py + 0.568 + 0.902p &= 0
\end{aligned}
\]

To solve this system, we can represent it in matrix form or directly manipulate the equations to isolate each variable step by step.

Let's proceed by solving this system of equations using a systematic approach.

### Step 1: Simplify the equations
Let's rewrite each equation by moving all terms involving \(p\), \(q\), \(x\), and \(y\) to one side and the constant terms to the other side.

1. \( -0.798p - 0.568q - 0.254qy + y = -0.6 \)
2. \( -0.502p - 0.822q - 0.296px + x = -0.6 \)
3. \( -0.798x - 0.502y + 0.032qx - 0.222qy + 0.968q = -0.502 \)
4. \( -0.822y - 0.568x - 0.198px + 0.098py + 0.902p = -0.568 \)

### Step 2: Solve the system
We will solve this system either by substitution, elimination, or matrix methods. I'll proceed with calculating the solutions.It seems that the system of equations has no solution when solved algebraically. This can occur if the equations are inconsistent, meaning they do not intersect at a common point in the space of the variables \(p\), \(q\), \(x\), and \(y\).

To explore further, one could:
1. Check if there's a mistake in the formulation of the equations.
2. Analyze if the system is over-constrained or under-determined.
3. Use numerical methods or an approximate solution to investigate the nature of the system.

Would you like to try numerical methods, or perhaps check for any errors in the equations?
