AEight methods
BSixty methods
CThree methods
DSeven methods
Answer & Solution
Correct answer: C. Three methods
1. Graphing is the first method to be introduced.
2. Substitution and elimination follow it.
3. Three methods in all are used to solve a system of linear equations.
4. So the answer is three.
