The system of equations displayed in your image is:

\[
\begin{aligned}
-x + 2y &= -6 \quad \text{(Equation 1)} \\
2x - 4y &= 12 \quad \text{(Equation 2)}
\end{aligned}
\]

### Step 1: Solve one of the equations for one variable.
We can solve Equation 1 for \(x\). Rewriting Equation 1:

\[
-x + 2y = -6
\]
\[
x = 2y + 6
\]

### Step 2: Substitute this into the second equation.
Now substitute \(x = 2y + 6\) into Equation 2:

\[
2(2y + 6) - 4y = 12
\]
\[
4y + 12 - 4y = 12
\]
\[
12 = 12
\]

### Step 3: Analyze the result.
The result \(12 = 12\) is a **true statement** for all values of \(y\). This means that the system has **infinitely many solutions** and is **dependent**.

### Solution:
Since the system is dependent, we express \(x\) in terms of \(y\). From Step 1, we already have:

\[
x = 2y + 6
\]

Thus, the solution set is:

\[
(x, y) = (2y + 6, y) \quad \text{for all real values of } y
\]

The answer you need to input for the dependent system should be:

\[
(2y + 6, y) \quad \text{where } y \in \mathbb{R}
\]

**Tip**: In a dependent system, both equations represent the same line, so the solutions will always be infinitely many.

Use the method of substitution to solve the following system of equations. If the system is dependent, express the solution set in terms of one of the variables. Leave all fractional answers in fraction form.
