Linear System Calculator: Solve Systems of Equations Effortlessly
Our Linear System Calculator helps you solve systems of linear equations quickly and accurately. Ideal for students, engineers, and professionals working with linear algebra.
What is a Linear System?
A linear system consists of two or more linear equations involving the same set of variables. Solving these systems is essential in fields like engineering, economics, and computer science.
History of Linear Algebra
Linear algebra has its roots in ancient mathematics, but it was formalized in the 17th century by mathematicians like René Descartes and Carl Friedrich Gauss. Today, it is a cornerstone of modern science and technology.
Applications of Linear Systems

Key Formulas
System of Equations:
a₁x + b₁y = c₁
a₂x + b₂y = c₂
Solution Methods:
- Substitution
- Elimination
- Matrix Methods (Cramer's Rule)
Practical Examples
Example 1: Solving a 2x2 System
Given:
2x + 3y = 5
4x - y = 1
Solution: x = 1, y = 1
Example 2: Real-World Application
