Solving Two-step Equations - Concept 67,371 views
Equations can be tricky, and solving two step equations is an important step beyond solving equations in one step. Solving two-step equations will help introduce students to solving equations in multiple steps, a skill necessary in Algebra I and II. To solve these types of equations, we use additive and multiplicative inverses to isolate and solve for the variable.
When you're trying to solve equations that have more than one step, there's a couple of things you want to keep in mind. The most important thing is that whatever you're doing to one side of the equation you need to do the exact same thing to the other side of the equation. Like if you're going to multiply on one side you have to multiply on the other side also that's the most important part for solving equations. What you want to keep in mind is what we call "Opposite Operations" in Math things like multiplying and dividing are opposites or adding and subtracting they are ways of like doing something and then undoing it. So when you have more than one step it's important to keep in mind the order of operations.
