About

In this session, we’ll focus on systems of equations and how to solve them algebraically without relying on graphs.

We’ll cover:
• What a system of equations represents
• Solving systems using substitution
• Solving systems using elimination
• How to check and interpret solutions
• Common mistakes and how to avoid them

This session builds on basic linear equations and is designed to strengthen problem-solving skills used in class and on exams.

SESSION 1

Functions and linear models

Functions and linear models

Thu 4:30 AM - 5:00 AM UTCDec 18, 4:30 AM - 5:00 AM UTC

This session is interactive and beginner-friendly. You don’t need to be confident with linear functions to join.

I’ll walk through examples step-by-step, explain why things work, and regularly pause for questions. You’re encouraged to ask questions, try problems, or just listen if you prefer.

The goal is for you to leave feeling more confident reading and graphing linear functions, not overwhelmed.

Tue 4:30 AM - 5:00 AM UTCDec 23, 4:30 AM - 5:00 AM UTC

This is an interactive, step-by-step session with worked examples and time for questions throughout. I’ll explain why each method works and how to decide which method to use.

You’re encouraged to ask questions or try problems along the way, but you’re also welcome to just listen and follow along. The goal is clarity and confidence, not speed.
