Transcript text: Solve the system by using any method. If a system does not have one unique solution, state whether the system is inconsistent or whether the equations are dependent.
\[
\begin{array}{l}
3 x-y=6 \\
x-\frac{1}{3} y=2
\end{array}
\]
Solution
Solution Steps
Step 1: Write the System of Equations
We are given the following system of equations:
\[
\begin{array}{l}
3x - y = 6 \\
x - \frac{1}{3}y = 2
\end{array}
\]
Step 2: Eliminate Fractions
To eliminate the fraction in the second equation, multiply the entire equation by 3:
\[
3(x - \frac{1}{3}y) = 3 \times 2
\]
This simplifies to:
\[
3x - y = 6
\]
Step 3: Compare the Equations
Now, we have the system:
\[
\begin{array}{l}
3x - y = 6 \\
3x - y = 6
\end{array}
\]
Both equations are identical, which means they are dependent.
Step 4: Determine the Nature of the System
Since the equations are dependent, the system has infinitely many solutions. The solution set can be expressed in terms of one of the variables.
Final Answer
The system has infinitely many solutions. The equations are dependent. The solution set is \(\boxed{\{(x, y) \mid 3x - y = 6\}}\).
