Elimination Method Calculator
Solve a 2×2 linear system by elimination (addition).
The elimination method multiplies the equations so that adding them removes one variable.
The math behind it
Multiply each equation by a constant so the coefficients of one variable are opposite, then add to eliminate it. Solve for the remaining variable and back-substitute.
Worked example
3x + 2y = 12 and x − 2y = 0 → add: 4x = 12, x = 3, y = 1.5.
FAQ
Elimination vs substitution?
Both give the same answer; elimination is handy when coefficients line up for easy cancellation.
