TODAY I AM NOT ALLOWED TO ANSWER ANY QUESTIONS DIRECTLY. IF YOU ASK ME A QUESTION I MIGHT ASK YOU ANOTHER QUESTION RATHER THAN ANSWER YOUR QUESTION
STARTER:
Problem 1
One day I went to a coffee shop and bought two coffees and 1 tea and was charged £1.40. Another day I went to the same coffee shop and bought 3 coffees and 1 tea and was charged £1.70

LESSON: Use Screen 4 from this MyMthas Lesson to generate lots of different example questions for them to have a go at. Let them develop a method. Get students up to IWB to explain how they got their results
EXTENSION: Ex 19J page 421 of higher text book
PLENARY: Write down in Your text book the method you used to solve the equations
