Teach it
Where it is taught, with guided notes, practice, homework, an exit ticket and an interactive Teacher Deck.
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.
