Algebra
2x2 System of Equations Solver
Solve a 2×2 system of linear equations in the form a₁x + b₁y = c₁ and a₂x + b₂y = c₂ using Cramer's rule. Returns the x-coordinate of the intersection of the two lines; foundational for any problem with two unknowns and two constraints.
Fill in the required fields to see your result.
Algebra
Matrix Determinant Calculator (2×2 and 3×3)
Calculates the determinant of a 2×2 or 3×3 matrix from its elements. Use it to check matrix invertibility, solve linear systems via Cramer's Rule, or compute areas and volumes in geometry.
