Solving the Equation: 2(3) + 3r = 12
Understanding how to solve linear equations is fundamental in algebra and forms the basis for many advanced math applications. One such equation frequently studied is 2(3) + 3r = 12. While seemingly simple, mastering this equation helps build strong problem-solving skills. In this article, weโll walk through the step-by-step process of solving 2(3) + 3r = 12, explain the algebra behind it, and highlight common pitfalls and best practices.
Understanding the Context
What Does the Equation 2(3) + 3r = 12 Mean?
The expression 2(3) + 3r = 12 combines constants, multiplication, and a variable, which alters how we approach solving for r. Parentheses must be evaluated first, followed by multiplication before addition or equating.
Step-by-Step Solution
Key Insights
Step 1: Evaluate the Multiplication Inside Parentheses
Start by simplifying the expression inside the parentheses:
2(3) = 6
Now rewrite the equation:
6 + 3r = 12
```
Step 2: Isolate the Variable Term
Subtract 6 from both sides to eliminate the constant on the left:
6 + 3r - 6 = 12 - 6 Divide both sides by 3:
3r = 6
Step 3: Solve for r
3r รท 3 = 6 รท 3
r = 2
Final Answer
r = 2

Why This Equation Matters
While 2(3) + 3r = 12 is a basic linear equation, solving it introduces key algebraic concepts:
- Order of operations: Parentheses before multiplication
- Isolating variables: Moving constants to the opposite side
- Balancing both sides: Maintaining equation integrity by performing identical operations
These skills are essential for solving more complex equations in algebra, such as those involving multiple variables or higher-degree polynomials.
Tips for Solving Similar Equations
- Always simplify expressions inside parentheses first.
- Perform multiplication or division before addition or subtraction.
- Keep one side of the equation isolated at each step.
- Check your answer by substituting r = 2 back into the original equation:
2(3) + 3(2) = 6 + 6 = 12 โ
