3x+2y=0

9x+6y=8

To solve the given system of equations using the **addition method** (also known as the elimination method), follow these steps:

### System of Equations:
\[
3x + 2y = 0 \tag{1}
\]
\[
9x + 6y = 8 \tag{2}
\]

### Step 1: Make the coefficients of \(x\) or \(y\) equal.
We can multiply equation (1) by \(-3\) to match the coefficients of \(x\) in both equations.

\[
-3(3x + 2y) = -3(0)
\]
\[
-9x - 6y = 0 \tag{3}
\]

### Step 2: Add the new equation to equation (2).
Now add equation (3) to equation (2):

\[
(-9x - 6y) + (9x + 6y) = 0 + 8
\]
\[
0 = 8
\]

### Step 3: Analyze the result.
The result, \(0 = 8\), is a **contradiction**. This means that the given system of equations is **inconsistent** and **has no solution**. The lines represented by these equations are parallel, so they do not intersect.

### Final Answer:
The system of equations has **no solution**.

### Tip:
When using the addition method, if the resulting equation is a contradiction (like \(0 = 8\)), the system has no solution. If you get a true statement (like \(0 = 0\)), the system may have infinitely many solutions.
