## 5. Assembly of system equation (cont'd)

${\text{S}}_{11}{\text{w}}_{1}={\text{f}}_{1}-{\text{S}}_{12}{\text{w}}_{2}\text{.}$
| (Eqn. 14) |

Any extra forces applied to individual nodes can also be added into
the right-hand side. The equation then represents the entire
boundary-value problem, and is solved using one of a variety of
techniques, such as Gauss-Jordan elimination.
