Critical thinking is really important when you're solving word problems that use linear equations. Let's break it down step-by-step:

1. Understanding the Problem: First, you need to read the question carefully. Make sure you understand what it's asking. Sometimes the math part is easy, but the story around it can be confusing. Try to simplify it by tackling one part at a time.

2. Identifying Variables: Next, figure out what the variables are. A variable is something that can change. Ask yourself, “What do I need to find out?” For example, if a problem says that John buys $x$ pencils for $2 each$, then $x$ is the variable you need to focus on.

3. Setting Up the Equation: This is where your critical thinking really matters. You have to turn the words into an equation. This means figuring out how things relate to each other. If John spends a total of $10, your equation would be$2x = 10$.

4. Solving & Interpreting: Now that you have the equation, it’s time to solve it! This might take a few steps. Make sure to check your answer and see if it makes sense in the context of the problem.

In summary, using critical thinking helps you see that you’re not just solving equations but really understanding what the problem is about. It makes everything clearer and a lot more fun!
