Answer is (C) (-1,3)
Beacuse, when you plug in these values, x = -1 and y = 3 in the given equations it satisfies both the equations. where as other ordered pairs are not true for both equations.

Hi
4x+3y=5 green line
-2x+5y=17 blue line
4x+ 3y=5
-4x+10y=34
13y = 39
y = 3 and x = (5-9)/4 = -1 | Using the 1st Eq
Solution is ordered pair Pt(-1,3)
