1 answer:
It appears you have the system with augmented matrxi ...
Right away, you notice that the 4th row is 3 times the 2nd row, so the equations are dependent and will not have a unique solution.
My calculator tells me the reduced equations can be written
... x1 -14x3 -19x4 = -8
... x2 -12x3 -16x4 = -7
This says there are two dependent equations in the set, not just one.

Answer:
(-4,1)
Step-by-step explanation:
Point A is located at (−2, −6), and D is located at (−6, 8).
We need to find the midpoint of A and D
Mid point formula is
Point A is (-2,-6) that is (x1,y1)
Point D is (-6,8) that is (x2, y2)
plug in the values in the formula
Mid point is (-4, 1)
