Algebra
System of Equations Solver
Solve simultaneous linear equations by entering the augmented matrix and applying Gauss–Jordan elimination.
Enter an augmented matrix (coefficients | constants) to solve Ax = b.
Gauss–Jordan reduction
Row operations transform the augmented matrix [A | b] into reduced row-echelon form, revealing the solution vector x.
How to use
- Enter each equation as a row of coefficients with the constant term last.
- Ensure every row has the same number of entries.
- Review the solved variables instantly or adjust the system if it’s singular.
Example
Input: 2 1 5\n1 −1 1
Output: x₁ = 2, x₂ = 1

Deep dive & study plan
The System of Equations Solver is a go-to tool whenever you need to solves linear systems using an augmented matrix.. It focuses on linear system, gaussian elimination, augmented matrix, which means searchers often arrive with intent-heavy queries like “how to system of equations solver quickly” or “system of equations solver formula explained.” Use this calculator to capture those intents and keep learners on the page long enough to send positive engagement signals.
Under the hood, the calculator leans on row operations transform the augmented matrix [a | b] into reduced row-echelon form, revealing the solution vector x.—that’s why we surface the full expression (“System of Equations Solver”) directly above the interactive widget. When you embed that formula inside H2s or supporting paragraphs, you help both humans and crawlers understand what entity the page represents.
Execution matters as much as the math. Follow the built-in procedure: Step 1: Enter each equation as a row of coefficients with the constant term last. Step 2: Ensure every row has the same number of entries. Step 3: Review the solved variables instantly or adjust the system if it’s singular.. Each numbered instruction is short enough to scan on mobile but descriptive enough to satisfy Google’s Helpful Content guidelines. Encourage students to jot down units, double-check signs, and compare answers with the Example card to build confidence.
The Example section itself is packed with semantic clues: “2 1 5\n1 −1 1” leading to “x₁ = 2, x₂ = 1.” Pepper similar narratives throughout your copy (and internal links from related guides) so canonical search intents are answered without pogo-sticking back to Google.
Quick retention checklist
- Speak the formula aloud (or annotate it) so the relationships stick.
- Write each step in your own words and compare with the numbered list above.
- Swap in new numbers for the Example to make sure the calculator (and your logic) handles edge cases.
- Link out to at least two related calculators to keep readers exploring your topical hub.
FAQ & notes
Can it detect infinite solutions?
If the system lacks a unique solution the solver flags the input so you can inspect the equations manually.
How many variables can it solve?
Use up to six variables comfortably. Larger matrices may amplify floating-point error.
What formula does the System of Equations Solver use?
Row operations transform the augmented matrix [A | b] into reduced row-echelon form, revealing the solution vector x.
How do I use the System of Equations Solver?
Enter each equation as a row of coefficients with the constant term last. Ensure every row has the same number of entries. Review the solved variables instantly or adjust the system if it’s singular.
