Roz's copy of Solve a pair of simultaneous equations
Solve for $x$ and $y$: \[ \begin{eqnarray} a_1x+b_1y&=&c_1\\ a_2x+b_2y&=&c_2 \end{eqnarray} \]
The included video describes a more direct method of solving when, for example, one of the equations gives a variable directly in terms of the other variable.

Julien's copy of Solve a linear programming problem
Student is given a set of constraints for a linear program. Asked to enter the constraints as inequalities, and then to identify the optimal solution.
Problem with solving the simultaneous equations gven by the constraints  too unwieldy and not given enough marks for doing so. Best if the point of intersection is given graphically by putting the mouse over the intersection.
