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

For Students:

  • Solve homework problems efficiently
  • Understand the basics of linear algebra
  • Prepare for exams with step-by-step solutions

For Professionals:

  • Optimize engineering designs
  • Solve economic models
  • Analyze data in machine learning algorithms

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

A company produces two products. The profit equations are:
P₁ = 3x + 4y
P₂ = 2x + 5y
Find the optimal production levels.
