Answer 1

Let's evaluate the steps in the process of solving the equation for \( x \): \( 2x + b = c \).

### Step-by-step Analysis:

1. **Step 1:** \( 2x + b - b = c - b \)
- This step is correct. You are isolating \( 2x \) by subtracting \( b \) from both sides.

2. **Step 2:** \( 2x = c - b \)
- This step is also correct. It simplifies the equation from Step 1.

3. **Step 3:** \( 2x - 2 = c - b - 2 \)
- This step contains an error. Instead of subtracting \( 2 \), you should be dividing both sides by \( 2 \) to isolate \( x \).

4. **Step 4:** \( x = \frac{c - b - 2}{2} \)
- This step would be incorrect as the previous step was already incorrect.

### Conclusion:
1. There is **no error** in Step 1.
2. There is **no error** in Step 2.
3. There is an **error** from Step 2 to Step 3.
4. There is an **error** from Step 3 to Step 4.

- The process has an error from step 3 to step 4.
