Consider a system of linear equations of the form

$\mathbf{A}\mathbf{x}=\mathbf{b},\mathbf{A}\in {\mathbb{R}}^{L\times K},\mathbf{x}\in {\mathbb{R}}^{L},\mathbf{b}\in {\mathbb{R}}^{K}$

with L variables$x}_{1},{x}_{2},\dots ,{x}_{L}\in \mathbb{R$ and $K\le L$ equations.

We are interested in finding a solution for a single variable x_l. Is there an explicit condition for existence of a unique solution for this variable?

Example: if${x}_{1}+2{x}_{2}+3{x}_{3}=3$ and $2{x}_{2}+3{x}_{3}=2$ , then there exist a unique solution ${x}_{1}=1$ for the variable $x}_{1$ , and we cannot find unique solutions for the other variables.

How would you solve the following system of linear equations:

$2{x}_{1}+(3+a){x}_{2}+2{x}_{3}=2+a$

${x}_{1}+a{x}_{2}+2{x}_{3}=a$

$a{x}_{1}+2{x}_{2}+2a{x}_{3}=0$

assuming that$a\ne \pm \sqrt{2}$ ? I feel confident in solving linear equation systems with just constants as the coefficients but the variable coefficient a is what gives me problems.

Here is the solution I find: solution as augmented matrix but how would the assumption about a make the reduced echelon form any different compared to an assumption about e.g.$a\ne \pm \sqrt{2}$ ?

In my understanding, a matrix is all of those:

1. a transformation in a vector space,

2. a function form some domain to some range,

3. a shorthand way of describing a system of linear equations.

By the last point, a real-valued matrix can have any conceivable real numbers as elements. Is that true or does there exist a table of numbers, which cannot be interpreted as a matrix in the linear algebra sense?

Quick way to check if a matrix is diagonalizable.

Is there any quick way to check whether a matrix is diagonalizable or not?

In exam if a question is asked like "Which of the following matrix is diagonalizable?" and four options are given then how can one check it quickly? I hope my question makes sense.
