Final Answer:

The solution (5, 3) corresponds to the system of linear equations:


\(2x + 4y = -8\)


\(3x + 5y = -15\)

Step-by-step explanation:

The given solution (5, 3) can be tested by substituting
\(x = 5\) and \(y = 3\) into the system of linear equations. For the first equation
\(2 * 5 + 4 * 3 = 10 + 12 = 22\) which does not equal -8.

For the second equation,
\(3 * 5 + 5 * 3 = 15 + 15 = 30\), which also does not equal -15. Therefore, (5, 3) is not a solution to the system of equations
\(2x + 4y = -8\) and \(3x + 5y = -15\).

Now, let's check the other given points:

For (-10, 4), the first equation yields
\(2 * (-10) + 4 * 4 = -20 + 16 = -4\), and the second equation gives
\(3 * (-10) + 5 * 4 = -30 + 20 = -10\). This satisfies both equations, making (-10, 4) a solution.

For (-10, 3), the first equation results in
\(2 * (-10) + 4 * 3 = -20 + 12 = -8\),and the second equation gives
\(3 * (-10) + 5 * 3 = -30 + 15 = -15\). This also satisfies both equations, making (-10, 3) a solution.

For (5, 5), the first equation yields
\(2 * 5 + 4 * 5 = 10 + 20 = 30\), and the second equation gives
\(3 * 5 + 5 * 5 = 15 + 25 = 40\). This does not satisfy either equation, so (5, 5) is not a solution.

Therefore, the correct solution is (-10, 4) and (-10, 3).
