🔹 What Is a System of Equations?

A system of equations is a set of two or more equations involving the same variables. The goal is to find values that satisfy all equations simultaneously.

For example:

1. 2x+y=102x + y = 102x+y=10
2. x−y=2x – y = 2x−y=2

This system requires solving for x and y such that both equations are true.

🔹 How a Systems Calculator Works

A Systems Calculator uses algebraic methods and matrix operations to solve equations. Methods include:

• Substitution method – solving one equation for a variable and substituting into the other.
• Elimination method – adding or subtracting equations to eliminate a variable.
• Matrix method (Gaussian elimination) – solving using advanced linear algebra.

You simply:

1. Enter your equations into the calculator.
2. Select the solving method (if available).
3. Get instant results with step-by-step solutions.

🔹 Example Calculation

Solve this system:

1. 3x+2y=123x + 2y = 123x+2y=12
2. x−y=4x – y = 4x−y=4

Step 1: From equation (2), x=y+4x = y + 4x=y+4.
Step 2: Substitute into equation (1): 3(y+4)+2y=123(y+4) + 2y = 123(y+4)+2y=12.
Step 3: Simplify → 3y+12+2y=123y + 12 + 2y = 123y+12+2y=12.
Step 4: 5y+12=12→y=05y + 12 = 12 → y = 05y+12=12→y=0.
Step 5: Substitute back → x=0+4=4x = 0 + 4 = 4x=0+4=4.

✅ Solution: x = 4, y = 0

The Systems Calculator would instantly give you this answer.
