Write any two solution of the equation `pix` + y = 9.

Answer

To find two solutions of the equation \( \pi x + y = 9 \), we can choose different values for \( x \) and \( y \) and solve for the other variable. Here’s a step-by-step solution:

### Step 1: Choose a value for \( x \)
Let's start by setting \( x = 0 \).

### Step 2: Substitute \( x = 0 \) into the equation
Substituting \( x = 0 \) into the equation gives:
\[ \pi(0) + y = 9 \]
This simplifies to:
\[ y = 9 \]

### Step 3: Write the first solution
So, the first solution is:
\[ (0, 9) \]

### Step 4: Choose a value for \( y \)
Now, let's choose a value for \( y \). We can set \( y = 0 \).

### Step 5: Substitute \( y = 0 \) into the equation
Substituting \( y = 0 \) into the equation gives:
\[ \pi x + 0 = 9 \]
This simplifies to:
\[ \pi x = 9 \]

### Step 6: Solve for \( x \)
Now, we solve for \( x \):
\[ x = \frac{9}{\pi} \]

### Step 7: Write the second solution
So, the second solution is:
\[ \left(\frac{9}{\pi}, 0\right) \]

### Final Answer
The two solutions of the equation \( \pi x + y = 9 \) are:
1. \( (0, 9) \)
2. \( \left(\frac{9}{\pi}, 0\right) \)
