Algebraic equations consist of two mathematical quantities, such as polynomials, being equated to each other. Solving equations yields a solution for the independent variables, either symbolic or numeric. In addition to finding solutions to equations, Wolfram|Alpha also plots the equations and their solutions.
Solve, plot and examine equations with one or more variables.
Find solutions to systems of congruence relations.
Solve a set of two or more simultaneous equations.
Use numerical approximation methods to solve an equation.
