What it does
For 2x + y = 5 and x − y = 1, enter "2 1 5" and "1 -1 1": coefficients first, constant last. Useful for Kirchhoff mesh and nodal analysis.
How to use it
- Write each equation as a row: coefficients then the constant.
- Solve.
- Read x₁, x₂ … in order.
Example
Solution: x₁ = 2, x₂ = 1. Select Try an example above to see it.
When it helps
- Mesh and nodal circuit analysis.
- Balancing chemical equations.
- Algebra homework.
Questions
What if there are infinitely many solutions?
The solver reports that there is no unique solution. Check whether two equations are multiples of each other.
Can I use fractions?
Yes, enter them as 1/3 and so on.
