First step is to multiply by 9 on each side.
First step is to multiply by 9 on each side.

First step is to add 32 to both sides.
First step is to add 32 to both sides.

The next step from F - 32 = 9/5 C, could be to multiply both sides by 5
The next step from F - 32 = 9/5 C, could be to multiply both sides by 5

The next step from F - 32 = 9/5 C, could be to divide both sides by 5
The next step from F - 32 = 9/5 C, could be to divide both sides by 5

Solution: 5/9F - 32 = C
Solution: 5/9F - 32 = C

To solve this equation for C, you would have to distribute at some point.

To solve the Celsius to Fahrenheit formula \( F = \frac{9}{5}C + 32 \) for \( C \), let's go through the steps.

1. **Start with the original equation**:
\( F = \frac{9}{5}C + 32 \)

2. **Subtract 32 from both sides**:
\( F - 32 = \frac{9}{5}C \)

3. **Multiply both sides by \( \frac{5}{9} \)** to isolate \( C \):
\( C = \frac{5}{9}(F - 32) \)

Which can also be written as:
\( C = \frac{5}{9}F - \frac{160}{9} \)

However, the expression \( C = \frac{5}{9}(F - 32) \) is the more common form to represent it.

### Checking the Given Responses

1. **First step is to multiply by 9 on each side.**
**False** - The first step involves subtracting 32, not multiplying.

2. **First step is to add 32 to both sides.**
**False** - You need to subtract 32 from both sides, not add.

3. **The next step from \( F - 32 = \frac{9}{5} C \), could be to multiply both sides by 5.**
**False** - The next step should be to multiply both sides by \( \frac{5}{9} \), not just 5.

4. **The next step from \( F - 32 = \frac{9}{5}C \), could be to divide both sides by 5.**
**False** - Dividing both sides by 5 does not isolate \( C \).

5. **Solution: \( \frac{5}{9}F - 32 = C \)**
**False** - This is not correct because it has \( -32 \) on the wrong side.

6. **To solve this equation for C, you would have to distribute at some point.**
**False** - The distribution is not necessary. You are simply calculating \( \frac{5}{9}(F - 32) \).

### Correct Solution

In summary, the correct answer (however not one of the provided options) should be:
**Solution: \( C = \frac{5}{9}(F - 32) \)**

None of the provided statements are true based on the correct steps needed to solve the equation.
