A solution to the system of equations is given by:
B. (-2,5)
The system of equations given is:
[tex]-4x + 3y = 23[/tex]
[tex]x - y = -7[/tex]
From the second equation:
[tex]x = y - 7[/tex]
Replacing in the first:
[tex]-4(y - 7) + 3y = 23[/tex]
[tex]-4y + 28 + 3y = 23[/tex]
[tex]-y = -5[/tex]
[tex]y = 5[/tex]
Then, for x:
[tex]x = y - 7 = 5 - 7 = -2[/tex]
Thus, a solution is (-2,5), given by option B.
