What students learn
Use mathematical modelling with linear, quadratic or exponential models to solve growth and decay problems, then evaluate and report on the model.
Worked example
Solve simultaneously: x + y = -11 and x - y = 5
Answer: x = -3, y = -8
Why: Adding the equations: 2x = -6, so x = -3. Then y = -11 - -3 = -8.
Generated and checked in code, so it is correct.
