5th HL Homework Group

Grind 10 in on solving 3 linear simultaneous equations and 3 unknowns.

The method is to eliminate one variable and get 2 equations with 2 unknowns. These are easily solved.

These questions come up a lot on Paper 1, usually Q1 (a). Practise the homework booklet attached to make sure you are fully confident with these. Could be worth 10-15 marks! 😀

We'll go through them in grinds next week.
