Answer:
(3,10) is not a solution of the given system.
Step-by-step explanation:
Testing the point (3,10) for the system of inequalities, where 3 is the x coordinate, and 10 the y-coordinate, then:
[tex]\left\{\begin{matrix}y &> 2x+3 & \\y& <3x+1 & \end{matrix}\right.\\10>2(3)+3\Rightarrow 10>9 \: False\\10>3(3)+1\Rightarrow 10 >10 \: False[/tex]
So the point (3,10) is not a solution of the given system.
