First equation 2(4X -5y = 4)
8X -10y = 8
Elimination 8x -10y =8
-8x + 9y =-8
-y =0
-1(-y =0)
y =0
8x -10(0) =8
8x =8
(8x =8)/8
x = 1

Answer:
(-1,3)
Step-by-step explanation:
The midpoint can be found with the formula {(x1 + x2 )/2, (y1 + y2.)/2 P1( x1 , y1 ), and P2 (x2 , y2 ) are the coordinates of two points, and the midpoint is a point lying equidistant and between these two points.
