X = -1162.5
Subtract 2,401 from both sides.
0 = 76 - 2401 - 2x
0 = -2325 - 2x
Add 2x on both sides.
2x = -2325
Divide both sides by 2.
x = -2325 / 2
x = -1162.5
There is the answer.

Answer:
The slope of this line would be undefined. 
Step-by-step explanation:
In order to find the slope of any line, use the slope formula. 
m(slope) = (y2 - y1)/(x2 - x1)
m = (3 - -1)/(-6 - -6)
m = (3 + 1)/(-6 + 6)
m = 4/0
Since we cannot divide by 0, then we know the slope is undefined.

I can only guess that you meant to write
12 + 3 = 3 + 12
which would be the commutative property of addition.
