Solving simultaneous equations

Mathematics teachers’ instructional strategies lack in-depth knowledge of algebraic systems and hold misconceptions about solving two algebraic equations simultaneously. This study aimed to gain an in-depth analysis of teachers’ knowledge and perceptions about the promotion of conceptual learning and effective teaching of algebraic equations.

This study analyses the hydrodynamic characteristic of the tilting pad thrust bearing. Research content is simultaneously solving the Reynolds equation, force equilibrium equation, and momentum equilibrium equations. Reynolds equation is solved by utilizing the finite element method with Galerkin weighted residual, thereby determines the pressure at each discrete node of the film. Force and momentums are integrated from pressure nodes by Gaussian integral.

Why are we interested in solving simultaneous equations? We often have to find a point which satisfies more than one equation simultaneously, for example when finding equilibrium price and quantity given supply and demand functions.  To be an equilibrium, the point (Q; P) must lie on both the supply and demand curves.  Now both supply and demand curves can be plotted on the same diagram and the point(s) of intersection will be the equilibrium (equilibria)

To simulate the incompressible flow in complex three-dimensional geometry efficiently and accurately, a solver based on solution of the Navier-Stokes equations in the generalized curvilinear coordinate system was developed. The system of equations in three-dimension are solved simultaneously by the artificial compressibility method. The convective terms are differenced using a flux difference splitting approach. The viscous terms are differenced using second-order accurate central differences. An implicit line relaxation scheme is employed to solve the numerical system of equations. ...
