Answer:
The answer is 3! I believe.
Step-by-step explanation:
The answer look at photo.
First we have to distribute the parentheses on the left side, 2*x is 2x and 2*-3 is -6, so now the equation is 4x+2x-6 = 8x+12
Then, we can add together the two x's on the left side,
so now we have 6x-6 = 8x+12 Subtract 12 from both sides and
you get 6x -18 = 8x Then you can subtract 6x from both the sides and get
-18 = 2x Now we can divide both sides by 2, and the final answer is -9 = x
Since they are not the same and the two sides aren't unequal, there is one solution(:

Answer:
The answer to your question is: Y = (13, -14)
Step-by-step explanation:
Data
midpoint = mp = (6, -3)
one endpoint = X = (-1, 8)
second endpoint = Y = (x, y)
Formula
Xmp = (x1 + x2) / 2
Ymp = (y1 + y2) / 2
Process
x2 = 2xmp - x1
y2 = 2ymp - y1
x2 = 2(6) - (-1) y2 = 2(-3) - 8
x2 = 12 + 1 y2 = -6 - 8
x2 = 13 y2 = - 14
Y = (13, -14)
