Answer:


This above options makes the expression true.
- The negatives above can be distributed up as well, which happened in A.
- In E, when the negatives inside the bracket cancels out, the negative outside the brackets multiplies and makes the expression true.
- In B the expression turns positive, thus false same happens with C and D
The answer would be 20.
How?

4x-3y-2=0 (2)
____________
6x -12=0 (if you just want the resulting equation. It is 6x-12=0)
x=2
take x=2 and put it into equation (2)
4(2) -3y -2=0
-3y= 2-8
y= 2
(x=2,y=2)
in parallelogram EFGH
the mid point of diagonal EG is
(-3-5)/2,(1+5)/2=(-4,3)
similarly the midpoint of diagonal FH is
(0-2)/2,(2+6)/2=(-1,4)
