-BARSIC- [3]

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:

$\left\{\begin{matrix}y &> 2x+3 & \\y& 2(3)+3\Rightarrow 10>9 \: False\\10>3(3)+1\Rightarrow 10 >10 \: False$

So the point (3,10) is not a solution of the given system.
