Step-by-step explanation:
the midpoint between 2 points (x1, y1) and (x2, y2) is simply ((x1+x2)/2, (y1+y2)/2).
so,
1.
(9, 7) to (4, -3)
midpoint is ((9+4)/2, (7+ -3)/2) = (13/2, 4/2) = (6.5, 2)
2.
(-7, -5) to (2, 1)
midpoint is ((-7+2)/2, (-5+1)/2) = (-5/2, -4/2) = (-2.5, -2)
3.
now we have the midpoint and need the second point.
(4, 2) over (3, 4) to (x, y)
3 = (4 + x)/2
6 = 4 + x
x = 2
4 = (2 + y)/2
8 = 2 + y
y = 6
4.
(-2, 1) over (-3, 2) to (x, y)
-3 = (-2 + x)/2
-6 = -2 + x
x = -4
2 = (1 + y)/2
4 = 1 + y
y = 3

Answer:
Y = 6
X = 24
Step-by-step explanation:
2x -5y = 16
(x -2y =5)*2
_______________
2x -5y = 16
2x - 4y = 10
_______________
(2x -5y = 16) - (2x - 4y = 10)
_______________
0x -y = 6
_______________
y =6
_______________
Replacing in equation 1:
2x - 5(6) = 16
so, 2x = 16 + 30
2x = 48
x = 24
