Algebra 1 · Systems of Equations & Inequalities
Definition
The elimination method solves a system by adding or subtracting the equations to eliminate one variable.
Examples
- Add x + y = 6 and x - y = 2 to get 2x = 8.
- Multiply an equation first if needed to line up a variable.
Key rule
Combine the equations so one variable cancels out.
Memory hook
Eliminate = cancel a variable by adding.
