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).

Problems

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.
