For Q3, you can subsitute x = 2 and y = 5 into the systems 
-5(2) + 5 = -5
so it's a solution for the first system
-4(2)+2(5) = 2
it's also a solution for the second system
 
        
             
        
        
        
Step-by-step explanation:
Given 
5x + 2x + 2 = 9x + 4
9x - 5x - 2x = 2 - 4
9x - 7x = - 2
2x = - 2
x = - 2 / 2
Therefore x = -1.
