Well to me he is one of the best teacher of Algebra on this is his confidence because other teachers have notes but he is doing it .................... and its natural you can make mistake and a mistake when you know every thing doesn't look bad. He is the best teacher i'm enjoing his classes and learning a lot. Thanks!

I was able to use the Example 2 strategy on a quiz and I was really happy when I found the correct answer, which is a sign that I'm beginning to understand more. Example 3 needs to be removed, it just confused me even more and it takes up too much time.

Techniques for Multi-Step Equations

  • A multi-step equation contains more than one operation.

  • To solve such an equation, undo the operations in the reverse order in which they were performed in the equation. The last operation performed in the equation is the first one to be removed, using the addition, subtraction, multiplication, and division properties of equality.

  • In most equations, the last operation performed is an addition or subtraction. Therefore, begin by using these properties of equality. Then use the multiplication or division property of equality to isolate the variable.

  • Understand how to solve word problems involving consecutive numbers. Consecutive unknown numbers are called x and x + 1. Consecutive unknown even or odd numbers are called x and x + 2.
