Answer: B
<u>Step-by-step explanation:</u>
  2x - 3y =  -7   →   2(2x - 3y = -7)   →   4x - 6y = -14
-4x + 6y = -10  →   1(-4x + 6y = -10) → <u>-4x + 6y</u> = <u>-10 </u>
                                                                     0  = -24
                                                                      FALSE
Since this makes a false statement, there are no solutions
 
        
             
        
        
        
The answer is $72
because if you subtract the discount by 96 you get 72
        
                    
             
        
        
        
The angles in a triangle always add up to exactly 180 degrees.  To see if this can be a triangle, add up the given angle measures.  If the sum is not 180, then it cannot be a triangle.
140+43+7=190
A triangle CANNOT have the angles measures as 140, 43, and 7.
Hope this helps!!
