Elimination Method
Example:
System: 2x + 3y = 7, x - y = 1
Step 1:
Step 2:
→ 5x = 10
Step 3:
Step 4:
Solution: x = 2, y = 1
When to use elimination:
- Coefficients are easy to cancel
- Both equations in standard form
- Works well with fractions
About Elimination Method Calculator
The Elimination Method Calculator solves systems of linear equations by adding or subtracting equations to eliminate one variable. Best used when coefficients align well or can be easily made opposite.
Advantages
- Systematic: Step-by-step method
- No fractions: Often avoids fractions until end
- Scalable: Works for larger systems
Types of Elimination
- Simple Addition: When coefficients are already opposite
- Simple Subtraction: When coefficients are the same
- With Multiplication: Multiply to make coefficients match
Frequently Asked Questions
How do I decide which variable to eliminate?
Choose the variable whose coefficients are easiest to make opposite through multiplication.
When should I add vs subtract equations?
Add when coefficients are opposite, subtract when they're the same.
