Question

Determine whether the ordered pair is a solution to the given system ofequations. (1,5) ; \begin{array}{l}
-5 m+6 n=25 \\
-7 m+8 n=33
\end{array} (-2,0) ; \begin{array}{l}
8 x-3 y=-16 \\
50=-9 x-2 y
\end{array} (7,-4) ; \begin{array}{l}
9 b+4 a=-8 \\
6 a+5 b-42=0
\end{array} (-3,-2) ; \begin{array}{l}
-7 c-4 d=29 \\
3 c=-7+d
\end{array} Check whether (6, 9) is a solution of the systems of linear equations. \begin{array}{l}
s+7 t=69 \\
6 t+4 s=78
\end{array} \begin{array}{l}
-2 p+5 q=34 \\
-7 q=-61-8 p
\end{array} Write a system of linear equations that has the solution (4, 3).
