No, No, Yes

Explanation:

In order to check if an ordered pair is a solution to a particular set of equations, you have to plug each number in (the ordered pairs take the format of #(X,Y)#) and see if the equations are still valid.
For the first problem: The ordered pair is #(4,3)#, meaning that #X=4 and Y=3#. Plug these values in to get #2(4)+5(3)=25, 8+15=25, 23!=25#, thus, the ordered pair is not a solution. Follow this same set of steps for the other two equations.
