The Wolfram Language has many powerful features that enable you to solve many kinds of equations. You can solve an equation using Solve. The result is a Rule inside a doubly nested list. The outer list holds all of the solutions and each inner list holds a single solution. Here there are three solutions:. To solve a system of equations, use a list in the first argument:. Here there are two solutions to a simultaneous system of equations; each solution set is wrapped in its own list:. Here the solution expresses one variable in terms of another:. To use one of these solutions here the first one is shown , use [ [ In a system of equations with multiple variables, you can solve for some or all of the variables by using a list in the second argument:. If the system is underspecified, the Wolfram Language will give an answer in terms of the remaining variables:. Solve finds what are known as "generic" solutions to equations. These are solutions that do not depend on the variables not specified in the second argument.

Introduced in 1.

Wolfram Alpha is capable of solving a wide variety of systems of equations. 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. Additionally, it can solve systems involving inequalities and more general constraints. Enter your queries using plain English. To avoid ambiguous queries, make sure to use parentheses where necessary. Here are some examples illustrating how to ask about solving systems of equations.

Solve verifies solutions obtained using non-equivalent transformations:. History Introduced in 1. Systems exp-log in the first variable and polynomial in the other variables:. In a system of equations with multiple variables, you can solve for some or all of the variables by using a list in the second argument:. The Wolfram Language also allows you to get numeric solutions for equations. Assumptions that contain solve variables are considered to be a part of the system to solve:. Give Feedback Top. Here Solve finds some solutions but is not able to prove there are no other solutions:. Other solutions that are only conditionally valid are expressed as ConditionalExpression objects. Solve may use non-equivalent transformations to find solutions of transcendental equations and hence it may not find some solutions and may not establish exact conditions on the validity of the solutions found. Use Normal to remove the conditions:. By default, Solve finds exact solutions of equations:.

Wolfram Alpha is a great tool for factoring, expanding or simplifying polynomials. It also multiplies, divides and finds the greatest common divisors of pairs of polynomials; determines values of polynomial roots; plots polynomials; finds partial fraction decompositions; and more. Enter your queries using plain English.

In a system of equations with multiple variables, you can solve for some or all of the variables by using a list in the second argument:. Real Equations in One Variable 13 Polynomial equations:. Root objects may involve parameters:. You can also get the numeric solution directly by using NSolve , which is faster than combining N and Solve :. Solve results do not depend on whether some of the input equations contain only parameters. The system is said to be inconsistent otherwise, having no solutions. Use FunctionBijective to test whether a function is bijective:. Solve deals primarily with linear and polynomial equations. Reduce and Solve additionally solve the resulting equations:. A single variable or a list of variables can be specified. The same problem can be expressed using ForAll and solved with Solve or Reduce :. More advanced methods are needed to find roots of simultaneous systems of nonlinear equations. More general systems involving nonlinear functions are possible as well. For univariate equations, Solve repeats solutions according to their multiplicity:. Modular Equations 4 Linear systems:.
