Section 3.6.2: Example Questions
To solve these examples you can
use either of the
web-based linear solvers in the lab (Section L1.2).
In the following examples, all symbols represent unknowns unless otherwise
stated. Some problems do not lead to solutions. The web solver
will in this case return all unknowns as zero and and print an error message.
The spreadsheet solver will produce error messages in the
solution cells. if this happens, look carefully at the
equations you have suppled and see why a solution could not be found.
