What methods can be used to solve a system of equations?

The answer depends on the nature of the equations. For a system of linear equations, the [generalised] inverse matrix is probably simplest. For a mix of linear and non-linear equations the options include substitution, graphic methods, iteration and numerical approximations. The latter includes trail and improvement. Then there are multi-dimensional versions of "steepest descent".


What are 2 symbolic techniques used to solve linear equations and which is better?

There are more than two methods, and of these, matrix inversion is probably the easiest for solving systems of linear equations in several unknowns.


How are linear equations used in business?

liner equations can b used in business for getting the rough estimate of the profit or loss using a variable in the place of a quantity which is unknown.


What are two symbolic techniques used to solve a system of linear equations in two variables?

I have never seen the term 'symbolic' used in this way. There are 4 methods used to solve a system of linear equations in two variables. Graphing, Substitution, Elimination, and Cramer's Rule.


How is linear equations used in archaeology?

The absorption of fluorine into flint dates exposure of the surface and dates the time the rock was cracked. The linear equation will compare the dates of exposure until today's date. There are other uses but that is one.

Elimination and substitution are two methods.


What is a real world example when the solution of a system of linear equations must be in the first quadrant?

usually used in science, distance versus time to find speed. distance on y-xis, and time on x-axis. the line represents speed. since neither time nor distance can be negative, the line will always be in the first quadrant.


How matrices used in engineering?

If you have a system, which can be expressed as a set of linear equations, then you can utilize matrices to help solve it. One example is an electrical circuit which uses linear devices (example are constant voltage sources and resistive loads). To find the current through each device, a set of linear equations is derived.


What are two symbolic techniques used to solve linear equations and which do you feel is better?
