Question

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

Answer 1

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)
