Step-by-step explanation:
Line A : x + y = 2
The most likely equation for line B so that the set of equation has no solution is:  
x + y = 4
====
x + y = 2
x = 2 - y
2-y + y = 4
0 = 4 - 2
0 ≠ 2
there is no value for x nor y. so, no solution.
 
        
             
        
        
        
Well the 2 is in the thousands and the number before it is six and because of the number before 2 happens to be over 5 the 2 changes into a 3 thus making your answer 133,000
        
                    
             
        
        
        
The answer would be 33 degrees.
        
             
        
        
        
Is the question how many such pieces of yarn will she have? 
We have to divide: 3 yards by 1/8th yard:
3/

dividing by a fraction means multiplying by its inverse!
