Sagot :
To start, let's analyze System A given by the equations:
[tex]\[ \begin{align*} 5x - y &= -11 \quad \text{(1)} \\ 3x - 2y &= -8 \quad \text{(2)} \end{align*} \][/tex]
We know that the solution to System A is [tex]\((-2, 1)\)[/tex].
Let's consider what happens if we replace the second equation in System A with the sum of the second equation and the first equation multiplied by a certain constant [tex]\(k\)[/tex].
To modify the second equation, we can write:
[tex]\[ k(5x - y) + (3x - 2y) = k(-11) + (-8) \][/tex]
By substituting the equations into this format directly, let's find the appropriate value of [tex]\(k\)[/tex] tested from the possible solutions.
### Case 1: Second equation in System B is [tex]\(-7x = 14\)[/tex]
We simplify the new second equation starting from \eqref{eq2}:
1. Start with [tex]\(k\)[/tex] as the multiplying constant
2. Combine equations by adding the modified first to the second.
3. Verify the resulting equation matches one of the provided options.
#### Using Given Solution - Check for Option Validity:
For [tex]\(\? = -7x = 14\)[/tex],
1. Start from System A:
[tex]\(\begin{array}{c} 5 x-y=-11 \tag{1} \\ 3 x-2 y=-8 \tag{2} \\ \end{array}\)[/tex]
2. Formulate Option:
Multiply (1) by [tex]\(k\)[/tex] and add to (2):
[tex]\(k(5x - y) + (3x - 2y)\)[/tex]- subset of [tex]\(5k+3)x-(k+2)y (\Left=-11k-8) For this to be useful Option Check by isolating new equivalent equation of -7x=14, calculate \(k\)[/tex]:
Notice by trial such [tex]\(x\)[/tex]:
[tex]\( -7x \)[/tex], resulting equate:
Let's find k by these given values,

[tex]\[ \begin{align*} 5x - y &= -11 \quad \text{(1)} \\ 3x - 2y &= -8 \quad \text{(2)} \end{align*} \][/tex]
