Substitution Method Calculator
Solve two linear equations with two variables using substitution, view the exact solution, verify both equations, and follow each algebra step.
Use standard form ax + by = c.
The calculator selects a practical substitution path.
See x, y, checks, and the full working.
A unique solution is the point where both lines intersect. If the equations describe the same line, there are infinitely many solutions. Parallel distinct lines have no solution.
What is the substitution method?
It isolates one variable in one equation and substitutes that expression into the other equation.
What does no solution mean?
The two equations represent parallel lines that never intersect.
What do infinitely many solutions mean?
Both equations represent the same line, so every point on that line satisfies both equations.
