MINI-PLENARY Simultaneous Equations Work out the value of one apple and one banana 9a + 3b = 105 3a + 3b = 51 Signs different (-) - 6a = 54 a = 9 Substitute in a = 9 27 + 3b = 51 b = 8 3b = 24

7. DISCOVERY Effective Participator Self Manager Independent Enquirer Creative Thinker Team Worker Reflective Learner Which ones are you using?PLT Skills LINK BACK TO OBJECTIVES - Accurately solve simultaneous equations where the coefficients of one variable is the same. What grade are we working at?

8. PLENARY ACTIVITY Solve the following simultaneous equation: 4x - 3y = 7 x + 3y = 13 Signs different (+) + 5x = 20 x = 4 Substitute in x = 4 16 - 3y = 7 y = 3 - 3y = -9

9. Draw your brain What have you learnt? In your brain, write or draw everything you can remember about solving simultaneous equations where the coefficients of one variable is the same. It can be a skill or a reflection, or something else that might be prominent in your brain. What grade are we working at? Where are we in our journey?
