Which Classification Describes the Following System of Equations?

Solving systems of equations can be a daunting task, especially when faced with various classifications. In this blog post, we’ll unravel the mystery of system classification and help you determine which type best fits your equations.

Struggling to Classify?

Whether you’re a student grappling with homework or an engineer solving complex problems, identifying the correct classification is crucial for efficient and accurate solutions. Different classifications represent distinct characteristics and solution methods.

Unveiling the Classification

The classification of a system of equations depends on the number of variables and equations involved. The following system:

2x + 3y = 5
-x + y = 2

has two variables (x and y) and two equations. This system falls under the classification of a: 2×2 System of Linear Equations


  • Systems of equations are classified based on the number of variables and equations.
  • The given system with two variables and equations is a 2×2 System of Linear Equations.
  • Understanding the classification of your system is essential for selecting the appropriate solution method.

System of Equations Classification

In mathematics, systems of equations are sets of two or more equations that must be solved simultaneously to find the values of the unknown variables. Depending on the number of variables and the nature of the equations, systems can be classified into various categories.

1. Linear Systems

Linear System Equation'

A linear system is a system of equations where all the variables have exponents of 1. They can be expressed in the general form:

a₁x + b₁y = c₁
a₂x + b₂y = c₂

2. Non-Linear Systems

Non Linear System Equation'

Non-linear systems involve equations where the variables have exponents greater than 1 or are part of trigonometric, exponential, or logarithmic functions. They cannot be solved using linear algebra methods.

3. Dependent Systems

Dependent System Equations'

Dependent systems occur when the equations represent the same line or plane. They have infinitely many solutions or no solutions at all.

4. Inconsistent Systems

Inconsistent System Equation'

Inconsistent systems arise when the equations represent parallel lines or planes. They have no solutions.

5. Consistent Systems

Consistent System Equation'

Consistent systems have at least one solution where the equations intersect. They can be further classified as:

– Independently: Equations with a unique solution.
– Dependent: Equations with infinitely many solutions.

6. Homogeneous Systems

Homogeneous System Equation'

Homogeneous systems are those where all the constants (c₁, c₂, …) are zero. They always have a trivial solution of (0, 0, …, 0).

7. Non-Homogeneous Systems

Non Homogeneous System Equation'

Non-homogeneous systems have at least one constant that is non-zero. They may or may not have solutions.

8. Square Systems

Square System Equation'

Square systems have the same number of variables as equations. They can be solved using determinants or matrix transformations.

9. Rectangular Systems

Rectangular System Equation'

Rectangular systems have a different number of variables than equations. They can be solved using matrices or Gaussian elimination.

10. Overdetermined Systems

Overdetermined System Equation'

Overdetermined systems have more equations than variables. They may or may not have solutions.

11. Underdetermined Systems

Underdetermined System Equation'

Underdetermined systems have fewer equations than variables. They have infinitely many solutions.

12. Simultaneous Equations

Simultaneous System Equation'

Simultaneous equations are systems where all the equations are expressed in terms of the same variable, often referred to as “x”.

13. Parameterized Equations

Parameterized System Equation'

Parameterized equations introduce a parameter, usually “t”, to represent the solutions. The variables are expressed as functions of the parameter.

14. Parametric Equations

Parametric Equation'

Parametric equations use a single parameter to represent the coordinates of a curve or surface. They are often used in calculus and geometry.

15. Vector and Matrix Formulations

Vector Matrix Equation'

Systems of equations can also be represented using vectors and matrices. This form is commonly used in linear algebra and computational mathematics.


The classification of systems of equations helps in understanding their characteristics, solvability, and methods of solution. It provides a framework for analyzing and solving various mathematical problems involving systems of equations.
