Solve any 2 by 2 or 3 by 3 system of equations step-by-step on AskSia. Choose substitution, elimination, graphing, or matrix methods, or let AskSia pick the cleanest one. Every solve shows the intersection point or lines graphed, and flags inconsistent or dependent systems automatically.
The AskSia system of equations solver is an AI tool that solves any 2 by 2 or 3 by 3 system step-by-step. Paste the equations, photograph them, or type them into the built-in calculator. AskSia picks the cleanest method (substitution when one variable is already isolated, elimination when coefficients line up, matrix methods for 3 by 3) or you can force a specific approach. Every solve returns the solution point, a graph of the lines, and a flag if the system has no solution (parallel lines) or infinite solutions (same line).
2 by 2 and 3 by 3 systems with substitution, elimination, graphing, matrix inverse, Cramer's rule, or Gaussian elimination. AskSia picks the right method for the system, or walks through the one your class is using.
When one variable is already isolated, AskSia uses substitution. When coefficients line up cleanly, it picks elimination. For 3 by 3 systems or messy coefficients, it switches to matrix methods. The choice is shown at the start of every solve.
Every 2 by 2 system solve comes with both lines graphed and the solution point labeled at the intersection. For 3 by 3 systems, AskSia shows a 3D plane view or the row-reduced matrix, depending on what's clearest.
When two equations describe parallel lines (no solution) or the same line (infinite solutions), AskSia flags it immediately and explains the geometric meaning, instead of returning a confusing 0 = 0 or 0 = 5.
Translate distance, age, mixture, and money word problems into systems automatically. AskSia identifies the two or three unknowns, builds the system, solves it, and interprets the values in context.
Ask for Gaussian elimination, the matrix inverse, or Cramer's rule. AskSia shows every row operation, computes the determinant, and explains why a singular matrix means no unique solution.
Photograph all the equations together, paste from an online homework portal, or type them into the built-in calculator. AskSia parses the system and lines up the variables automatically.
Snap a photo with all equations visible, paste them, or type them into the built-in calculator. AskSia parses the system and identifies the variables.
AskSia chooses substitution, elimination, graphing, or matrix methods based on the system. You can override and request any specific method, useful when your class is being taught one technique.
AskSia returns the solution point with both lines graphed, or shows the row-reduced matrix for 3 by 3 systems. The intersection or 3D plane is labeled, with the algebraic answer alongside.
Every solve syncs across Web, iOS, and Android — start it at your desk, finish on your phone.
Split-panel interface with the worked solution on the left, the auto-generated diagram and AI tutor chat on the right.
Open the camera, frame the problem, and the worked solution plus diagram appear in seconds.
2 by 2 linear systems solved by substitution, elimination, or graphing. AskSia picks the cleanest method and shows the solution point on a graph, with both lines labeled.
3 by 3 linear systems with messy coefficients. AskSia switches to matrix methods (Gaussian elimination, inverse, or Cramer's rule) and shows every row operation.
Distance-rate-time, age, mixture, money, and work problems that require 2 or 3 unknowns. AskSia identifies the unknowns, builds the system, and interprets the answer in the original context.
First-semester Linear Algebra problems involving systems and row reduction. AskSia walks through Gaussian elimination with every elementary row operation labeled and the augmented matrix shown at each step.
Systems with no solution (parallel lines) or infinite solutions (same line) are flagged at the start, with the geometric meaning explained. Useful when a homework problem expects you to identify the type.
Systems of equations are SAT and ACT staples. After any solve, generate similar practice problems at the right difficulty level for your target exam.
