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.

Our last two grinds are on Algebra Revision for your summer exams!

 We will cover ALL algebra for paper 1, including, Factor theorem, Logs, Inequalities, Simultaneous linear and non linear, rationalising denominators, proof of root 2, solving quadratics and cubics.....😀
