Solving #

We are looking for a vector linear_system_of_equations_e2c1566780213d21ef119b43c358a8260eb7e420.svg that solves all of the eqations. The same problem can also be expressed in an equivalent matrix form.

For solving, this is often condensed into one augmented matrix:

The goal is to get the matrix into a form where the left hand side is the identity matrix. In that case, the right side will be the solution vector.
