Students learn how to solve a pair of simultaneous equation using the elimination method.

Later, as learning progresses they solve equations with different coefficients.

**Differentiated Learning Objectives**

- All students should be able to solve a pair of equations simultaneously using the method of elimination given equal coefficients of one unknown.
- Most students should be able to solve a pair of equations simultaneously using the method of elimination where one coefficient is a factor of the other.
- Some students should be able to derive and solve a pair of equations simultaneously using the method of elimination where one coefficient is a factor of the other.
