When converting a linear equation into an augmented matrix, which equation form is needed

For this case, what you need is to write an equation of the form:

Ax = b

Where

A = coefficient matrix of the unknowns of the linear system of equations.

x: unknowns vector

b: vector solution of each equation of the linear system.

The augmented matrix is

(A l b)

answer

Ax = b

Augmented matrix:

(A l b)
