Hi,
-2x - 9y = -25
-4x - 9y = -23 

-2x - 9y = -25    
<u>-(-4x - 9y = -23)</u>   |subtracting the 2nd EQ from the 1st to eliminate y
-2x - 9y = -25    
<u>4x + 9y =23)</u>
   2x  = -2
     x = -1    and y = 3  {{{ 4 - 9y = -23}}},  9y = 27 , y = 3
Pt (-1, 3) the solution for this system of Equations
CHECKING our answer***
Using -2x - 9y = -25
        2 -27 = -25
