To solve a system of equations by elimination, write the system of equations in standard form: ax + by = c, and multiply one or both of the equations by a constant so that the coefficients of one of the variables are opposite.

Free Systems of Equations Calculator helps you solve sets of two or more equations. Linear, nonlinear, inequalities or general constraints. Answers, graphs, alternate forms.

Shows you step-by-step how to solve systems of equations! This calculator will solve your problems.

This solver (calculator) will try to solve a system of 2, 3, 4, 5 equations of any kind, including polynomial, rational, irrational, exponential, logarithmic, trigonometric, hyperbolic, absolute value, etc.

A system of equations is a collection of equations that are in terms of the same set of variables. Our goal is to try to find a solution set of variables that satisfies every equation in the system. Learn how to solve system of linear equations using different methods.

This calculator solves Systems of Linear Equations with steps shown, using Gaussian Elimination Method, Inverse Matrix Method, or Cramer's rule. Also you can compute a number of solutions in a system (analyse the compatibility) using Rouché–Capelli theorem .

We can solve systems of two equations using three main methods: elimination, substitution, and graphical methods. Here, we will focus on the elimination method and the substitution method. We can follow the following steps to solve the system by substitution:
