Solving 1 and 2 Step Equations: Key Techniques and Examples

The video tutorial covers solving one-step and two-step equations. It begins with basic principles of maintaining balance in equations and progresses through examples involving addition, subtraction, multiplication, and division. The tutorial emphasizes the importance of performing the same operation on both sides of the equation to isolate the variable. It concludes with a brief introduction to multi-step equations and encourages viewers to continue learning.

What must be true about the left and right sides of an equation?

• They must be positive.

• They must be negative.

• They must be different.

• They must be equal.

If you are adding a number to one side of an equation, what should you do to the other side to keep it balanced?

• Add the same number.

• Subtract the same number.

• Divide by the same number.

• Multiply by the same number.

What is the opposite operation of division?
