Solve the following systems of equations using the substitution and elimination methods.
Solution
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.
System (a):
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)**:
$$\begin{cases}
x + 2y = 6 \\
2x + 3y = 7
\end{cases}$$
