2 STEP EQUATIONS WITH DISTRIBUTIVE PROPERTY: Everything You Need to Know
2 step equations with distributive property is a fundamental concept in algebra that requires a solid understanding of the distributive property and the ability to solve equations with two steps. In this comprehensive guide, we will break down the concept of 2 step equations with distributive property, provide practical information, and offer tips and strategies to help you master this essential skill.
Understanding the Distributive Property
The distributive property is a fundamental concept in algebra that states that for any numbers a, b, and c, the following equation holds true:
- a(b + c) = ab + ac
- (a + b)c = ac + bc
This property allows us to distribute a single term across the terms inside the parentheses. For example, if we have the equation 2(x + 3), we can use the distributive property to rewrite it as 2x + 6.

It's essential to understand the distributive property to solve 2 step equations with distributive property, as it allows us to simplify the equation and isolate the variable.
Solving 2 Step Equations with Distributive Property
To solve a 2 step equation with distributive property, we need to follow these steps:
- Apply the distributive property to simplify the equation.
- Combine like terms.
- Solve for the variable.
Let's consider an example: 2(x + 3) = 12. To solve this equation, we can use the distributive property to rewrite it as 2x + 6 = 12.
Next, we can combine like terms by subtracting 6 from both sides of the equation, resulting in 2x = 6.
Finally, we can solve for the variable by dividing both sides of the equation by 2, resulting in x = 3.
Examples of 2 Step Equations with Distributive Property
Here are some examples of 2 step equations with distributive property:
| Equation | Step 1: Apply Distributive Property | Step 2: Combine Like Terms | Step 3: Solve for Variable |
