For this one a simple way that you can think of it is that 1 pound of banana is equivalent to 100, 3/4 pounds of banana is 75, 1/2 pounds of banana is 50, etc. 
3 1/2 pounds of banana = 350 
3/4 pounds of banana = 75 
If i want to find out how many loafs of banana bread I can make if ONE loaf requires 3/4 pounds of banana, and i have 3 1/2 pounds of banana then I divide:
350 / 75 = 4.66 
So, with 3 1/2 pounds of bananas you can successfully create 4 loafs of banana bread. the remaining .66 is not enough banana to make another loaf. 
        
                    
             
        
        
        
Answer:
6 meters 
Step-by-step explanation:
i see it on the picture and yeah and i did the math
 
        
             
        
        
        
You can do 
83 - 5 to find the answer
So that's 
78 or 
5 + 78 = 83
        
                    
             
        
        
        
So we are given a system:

Substitute x = 2 we get the system:

Multiply the first equation by -5 and the second by 2 we get the system:

Adding the two equations we get :

We find the value of y by using any of the other equations like this:

Final solution:
