The image contains two sets of systems of linear equations in Vietnamese, which are to be solved using different methods.

### **Bài 1**: Solve the systems of equations using the substitution method.
1. **System (a)**:
\[
\begin{cases}
x + y = 5 \\
4x - 3y = -1
\end{cases}
\]

2. **System (b)**:
\[
\begin{cases}
x - 2y = 2 \\
2x - 4y = 4
\end{cases}
\]

3. **System (c)**:
\[
\begin{cases}
8x - 2y = 10 \\
-4x + y = 3
\end{cases}
\]

### **Bài 2**: Solve the systems of equations using the elimination method.
1. **System (a)**:
\[
\begin{cases}
-2x + 3y = 5 \\
4x - 3y = -1
\end{cases}
\]

2. **System (b)**:
\[
\begin{cases}
x - 2y = 2 \\
2x - 4y = 4
\end{cases}
\]

3. **System (c)**:
\[
\begin{cases}
x + 2y = 6 \\
2x + 3y = 7
\end{cases}
\]
