LEARNING OBJECTIVE: To discover how to use an alternative method (Substitution) to solve a simultaneous equation problem
SUCCESS CRITERIA: You will be able to solve simultaneous equation problems using any method we have covered.
STARTER: Screen 5 from this MyMaths Lesson
LESSON: Video 1,
Example Solve x - y =12 and 3x + 2y = 46
Solve Ex 19L
Q7 2x + y = 4, and x – y = 5
Q 15 x – 5y = 15 and 3x – 7y = 17
Q1 page 425 (briefly looked at yesterday) solve on IWB
Work through Ex 19M page 425.
PLENARY: Checking answers – look at Q ?? From Practice Paper 2. Can you solve it now?
