Simultaneous equations are two or more equations with two or more variables. They are simultaneous because they can be solved to give values for the variables that are equal in each equation. This is ...

with B * = I- B. This requires that one of the preceding equations be solved for P t. Solving the second equation for P t yields You can estimate the intercepts of a system of simultaneous equations ...

Over the last few issues, we've been talking about the math entity called a matrix. I've given examples of how matrices are useful and how matrix algebra can simplify complicated problems. A messy ...
