### demand equation and a supply equation which explain the price and quantity of commodity exchanged in the market at market equilibrium. So there are two equations to explain the whole phenomenon - one for demand and another for supply. In such cases, it is not necessary that all the variables should appear in all the equations.

Lunar theory attempts to account for the motions of the Moon.There are many small variations (or perturbations) in the Moon's motion, and many attempts have been made to account for them.After centuries of being problematic, lunar motion is now modeled to a very high degree of accuracy (see section Modern developments).. Lunar theory includes: Herman Ole Andreas Wold (25 December 1908 – 16 February 1992) was a Norwegian-born econometrician and statistician who had a long career in Sweden.Wold was known for his work in mathematical economics, in time series analysis, and in econometric statistics..
