Hello!
Since D is the midpoint and the two equations are and both sides of point D the equations equal each other
9x - 7 = 3x + 17
Now you solve it algebraically
Add 7 to both sides
9x = 3x + 24
Subtract 3x from both sides
6x = 24
Divide both sides by 6
x = 4
Now we put this into both equations and add them
9(4) - 7 = 29
3(4) + 17 = 29
29 + 29 = 58
The answer is 58 units
Hope this helps!

Answer:
20
Step-by-step explanation:
x = price
y = number of keyboard
xy = 540
(x-2)(y+3) = 540
x = 540/y
==> x = 20
==> y = 27
8.4/4.8=y/14.4
y=25.2
Here is the answer
