Question
**Exercise 20: Solving Linear Algebraic Equations**

**Objective:** Solve the equations \(Ax = b\), where 

Matrix \(A\) is:
\[
A = \begin{bmatrix}
3.50 & 2.77 & -0.76 & 1.80 \\
-1.80 & 2.68 & 3.44 & -0.09 \\
0.27 & 5.07 & 6.90 & 1.61 \\
1.71 & 5.45 & 2.68 & 1.71 \\
\end{bmatrix}
\]

Vector \(b\) is:
\[
b = \begin{bmatrix}
7.31 \\
4.23 \\
13.85 \\
11.55 \\
\end{bmatrix}
\]

**Instructions:** By computing the determinant \(|A|\) and the product \(Ax\), comment on the accuracy of the solution.

**Note:** Use Python code to assist in solving these equations and verify the results.
