gaussianElimination is a function that takes a matrix as input and performs Gaussian Elimination to solve the system of linear equations. The function modifies the input matrix by applying row operations to reduce it to an upper triangular form, and then uses back$-$subsitution to solve for the unknowns. The function returns a list $($or array$)$ of solutions corresponding to the unknown variables in the system. Please solve using Python code below.

def gaussian$\_$elimination$($matrix$)$:

$"$u$"$

Performs Gaussian Elimination to solve a system of linear equations.

Parameters:

matrix $($list of list of floats$)$: A $2$D list where each inner list represents

an equation and each element corresponds to a

coefficient or constant of the equation.

The last element of each inner list is the constant.

Returns:

list of floats: A list representing the solution to the system of equations.

Each element corresponds to the value of a variable.
