Let's start by solving the first equation for \( y \).
Question 1: Solve the equation \( 4y = 3x \) for \( y \).
To isolate \( y \), we divide both sides of the equation by 4:
\[ y = \frac{3x}{4} \]
This can also be expressed as:
\[ y = \frac{3}{4}x \]
So the correct response is:
- \( y = \frac{3}{4}x \)
Question 2: Analyze the process of solving \( 2x + b = c \).
The steps given are:
- \( 2x + b - b = c - b \)
- \( 2x = c - b \)
- \( 2x - 2 = c - b - 2 \)
- \( x = \frac{c}{2} - \frac{b}{2} - 1 \)
Let's evaluate each step:
Step 1: Correctly subtracting \( b \) from both sides.
- This step is correct.
Step 2: Simplifying the equation to isolate \( 2x \).
- This step is also correct.
Step 3: Trying to move from \( 2x = c - b \) to a new equation \( 2x - 2 = c - b - 2 \).
- This step introduces an error because it inaccurately manipulates the equation. You can only subtract the same value from both sides, and subtracting 2 from \( 2x \) without doing the same to the \( c-b \) side is incorrect.
Step 4: Therefore, this step is based on the previous error and is incorrect.
Conclusion:
- The answers regarding the correctness of the process are:
- The process has an error from step 2 to step 3
- The process has an error from step 3 to step 4
Thus, the correct true statements from the given options are:
- The process has an error from step 2 to step 3
- The process has an error from step 3 to step 4
The other choices stating there is no error in the entire process are false.
