Step 6: Hence, the solution for the given simultaneous equations is a = 3 and b = 0. The explanatory variables in the model are specified before-hand, and the sign and/or magnitude of the relationship between every single explanatory variable and the dependent variable are clearly established so as to not cause any confusion. It is used mainly, however, by economists to study relationships between economic variables.
