Solving systems of equations is a very general and important idea, and one that is fundamental in many areas of mathematics, engineering and science. Going further, more general systems of constraints are possible, such as ones that involve inequalities or have requirements that certain variables be integers. These possess more complicated solution sets involving one, zero, infinite or any number of solutions, but work similarly to linear systems in that their solutions are the points satisfying all equations involved. More general systems involving nonlinear functions are possible as well. Systems of linear equations involving more than two variables work similarly, having either one solution, no solutions or infinite solutions (the latter in the case that all component equations are equivalent). The system is said to be inconsistent otherwise, having no solutions. If all lines converge to a common point, the system is said to be consistent and has a solution at this point of intersection. In the case of two variables, these systems can be thought of as lines drawn in two-dimensional space. Find more Mathematics widgets in WolframAlpha.

To solve a system is to find all such common solutions or points of intersection. The solutions to systems of equations are the variable mappings such that all component equations are satisfied-in other words, the locations at which all of these equations intersect. WolframAlpha can solve many problems under this important branch of mathematics, including. It can be referred to as an ordinary differential equation (ODE) or a partial differential equation (PDE) depending on whether or not partial derivatives are involved. What are systems of equations? A system of equations is a set of one or more equations involving a number of variables. A differential equation is an equation involving a function and its derivatives.

Here are some examples illustrating how to ask about solving systems of equations. To avoid ambiguous queries, make sure to use parentheses where necessary. Additionally, it can solve systems involving inequalities and more general constraints.Įnter your queries using plain English. It can solve systems of linear equations or systems involving nonlinear equations, and it can search specifically for integer solutions or solutions over another domain. Wolfram|Alpha is capable of solving a wide variety of systems of equations. Equation 4: Compute A powerful tool for finding solutions to systems of equations and constraints
