Sagot :

Let's solve each system of equations pair by pair to match them with the appropriate solution:

1. System 1:
[tex]\[ \begin{cases} 4x - 3y = -1 \\ -3x + 4y = 6 \end{cases} \][/tex]
This system has a unique solution which is [tex]\((2, 3)\)[/tex].

2. System 2:
[tex]\[ \begin{cases} 3x - 2y = -1 \\ -x + 2y = 3 \end{cases} \][/tex]
This system has a unique solution which is [tex]\((1, 2)\)[/tex].

3. System 3:
[tex]\[ \begin{cases} 3x + 6y = 6 \\ 2x + 4y = -4 \end{cases} \][/tex]
This system has no solution because the lines represented by these equations are parallel.

4. System 4:
[tex]\[ \begin{cases} -3x + 6y = -3 \\ 5x - 10y = 5 \end{cases} \][/tex]
This system has infinitely many solutions because both equations represent the same line.

Matching the systems with the appropriate solutions:

1. System:
[tex]\[ \begin{cases} 4x - 3y = -1 \\ -3x + 4y = 6 \end{cases} \][/tex]
Solution: [tex]\((2, 3)\)[/tex].

2. System:
[tex]\[ \begin{cases} 3x - 2y = -1 \\ -x + 2y = 3 \end{cases} \][/tex]
Solution: [tex]\((1, 2)\)[/tex].

3. System:
[tex]\[ \begin{cases} 3x + 6y = 6 \\ 2x + 4y = -4 \end{cases} \][/tex]
Solution: No solution.

4. System:
[tex]\[ \begin{cases} -3x + 6y = -3 \\ 5x - 10y = 5 \end{cases} \][/tex]
Solution: Infinite number of solutions.

Thus, the correct matches are:

- [tex]\[ \begin{cases} 4x - 3y = -1 \\ -3x + 4y = 6 \end{cases} \][/tex]
matched with: [tex]\((2, 3)\)[/tex].

- [tex]\[ \begin{cases} 3x - 2y = -1 \\ -x + 2y = 3 \end{cases} \][/tex]
matched with: [tex]\((1, 2)\)[/tex].

- [tex]\[ \begin{cases} 3x + 6y = 6 \\ 2x + 4y = -4 \end{cases} \][/tex]
matched with: No solution.

- [tex]\[ \begin{cases} -3x + 6y = -3 \\ 5x - 10y = 5 \end{cases} \][/tex]
matched with: Infinite number of solutions.
