Solving Two-Step Equations in Algebra

The video tutorial teaches how to solve two-step equations, using an example where the variable is on the right side. It explains the process of isolating the variable by performing inverse operations, such as addition and division, to both sides of the equation. An alternative method is also demonstrated, showing that the variable's position does not affect the solution. The tutorial concludes with a verification of the solution and emphasizes the simplicity of math.

What is the initial position of the variable in the equation discussed?

• No variable present

• Both sides

• On the right side

• On the left side
