LINK BACK TO OBJECTIVES - Accurately solve simultaneous equations where the coefficients of one variable is the same. What grade are we working at?

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

What have you learnt? Draw your brain 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. Where are we in our journey? What grade we working at?
