Lesson 4: Solving linear equations. Pythagorean Theorem
Here is a PDF version of the lesson.
Here is a PDF version of the workbook containing lots of practice.
In this lesson you will learn how to solve one step and multi step linear equations.
For example, x – 3 = 10 or 2h + 1 = – 9.
The lesson demonstrates how to solve linear equations with brackets.
For example, 2(x – 1) = 16.
You will also discover the Pythagorean Theorem.
You will learn when and why to use it, how to set it up and solve the equation.
The challenge of solving the Pythagorean Theorem is that it involves squares and it is important to follow the equation solving algorithm carefully in order to avoid mistakes.
Additional practice will help you master the skills.
