Answer:
6 or
 or  feet per inch
 feet per inch
Step-by-step explanation:
Yeah. This is a question about scaling. 
Basically, it's asking how many feet (in real life) are being represented by one inch in the blueprint.
You solve it by dividing the height of the actual house by the height of the blueprint. And, since the actual house is in feet, and the blueprint is in inches, your answer will be in feet per inches.
Does that help?
 
        
                    
             
        
        
        
Well to eliminate x you will need to make the positive value of x in one equal the negative value in the other. 
hence you can either multiply A by 5/2 or B by 2/5 which brings you to either 2 or 3, but as x is negative in B already, you add. resulting in the answer being the 3rd one down (i think)
