I have ‘my take’ on the best approach to solving simultaneous equations by looking at the ‘Lowest Common Multiples’ (LCMs). I have found that this makes such a difference to the middle to weaker students in their understanding and proficiency.

If you are searching for my videos as topics in a playlist on Rumble, you can type in eg:
RobertPrestwidge Equation
RobertPrestwidge Trigonometry
RobertPrestwidge Fraction
Also Logs, Parabola, Quadratic, Index Laws, Exponents, Calculus, Surd, Order of Operations, Simultaneous Equations, Negatives, Trinomials, Factorising and many other Math topics.

You can also find me on Youtube where my videos are organised into Playlists ie Topics.

This contains further examples of how to solve 2 Simultaneous Equations using the 'Elimination Method' with more focus on some of the tricky cases where students commonly make errors.

From my experience, the biggest secret is to watch each video 3 times across a week or more (which very few people do with anything, not just Maths). I have tried to make this easier by keeping these videos quite brief.

After 40 years of enjoyable and rewarding teaching, I still love and continue to teach. It still amazes me how I continue to still think of better ways of teaching mathematical concepts and I also continue to discover methods of explaining things that help students 'better' understand and become more successful at remembering the concepts.

A word of warning from what I have repeatedly seen over the years - most of my videos are placed in a logical or reasonably sequential order and if you watch the first or second video in a playlist and feel comfortable with the concepts, please go to the last video in the playlist to check if you really are okay. Each video in a playlist usually becomes progressively more complex and the 'latter' or 'last' video will often contain common assessment questions where students are known to make errors.

I also often include some revision / consolidation / mixture videos in the playlist which I know are crucial to assist with student success in assessments.

I hope that you find this very helpful and a blessing in your studies.
