Linear Equation(Two & Three Variables) Calculator

This Linear Equation Calculator is a powerful tool designed to help students, engineers, and professionals solve systems of linear equations with two or three variables quickly and accurately.

Whether you’re checking homework, verifying engineering calculations, or exploring algebraic solutions, this calculator provides instant results and saves you time.

How to Use the Linear Equation Calculator

Choose the Type of Equation:

• Select either 2 variables or 3 variables based on your equation system.

Enter the Coefficients:

• For each variable and the constant on the right side of the equation (e.g., for Ax + By = C), input the values A, B, and C.

Click “Calculate”:

• The calculator will automatically solve the system and display the values of x, y, and z (if applicable).

Example (2 Variables):
Equation 1: 2x + 3y = 13
Equation 2: 4x – y = 5

Just enter the values:
A1 = 2, B1 = 3, C1 = 13
A2 = 4, B2 = -1, C2 = 5

Click calculate — and you’ll get the exact values of x and y.

Why Use This Calculator?

• Accurate Solutions for systems of linear equations
• Fast and Easy to Use — ideal for exams, homework, or technical work
• Solves Both 2×2 and 3×3 Systems
• Eliminates Manual Errors
• Saves Time, especially for complex problems

📚 What Are Linear Equations in Two or Three Variables?

A linear equation in two variables has the form:

Ax + By = C

In three variables:

Ax + By + Cz = D

Solving them means finding values of x, y, and z that satisfy all given equations simultaneously.
