Answer:
X = -3
Step-by-step explanation:
X/2-5 = 1
X/-3 = 1
Multiply both sides by -3 to isolate x
X = -3
 
        
             
        
        
        
Answer:
 each pair of distinct vertices we connect them up with
 a line segment. There are (8 2 )=28 such line segments.
Step-by-step explanation:

-7x+y=42
y=42+7x 
5x+13y=66
Substitute for y (meaning put 42+7x into the equation above instead of y because they are equal - see second line of my answer above)
5x+13[42+7x]  = 66
5x +546 = 66
5x=66-546
5x=-480
x=-480/5
x=-96
