Which of these is NOT an algebraic method of solving a pair of linear equations?
Acompleting the square method
Bsubstitution method
Celimination method
Dcross-multiplication method
Answer & Solution
Correct answer: A. completing the square method
1. The standard algebraic methods are substitution, elimination and cross-multiplication.
2. **Completing the square** is a method for quadratic equations, not linear pairs.
3. The graphical method is separate from these algebraic ones.
