Hope these help but i wrote all of it out with all its geometrical reasons
 
        
             
        
        
        
Answer:
{d,b}={4,3}
Step-by-step explanation:
 [1]    11d + 17b = 95
   [2]    d + b = 7
Graphic Representation of the Equations :
    17b + 11d = 95        b + d = 7  
  
 
Solve by Substitution :
// Solve equation [2] for the variable  b 
 
  [2]    b = -d + 7
// Plug this in for variable  b  in equation [1]
   [1]    11d + 17•(-d +7) = 95
   [1]    -6d = -24
// Solve equation [1] for the variable  d 
   [1]    6d = 24 
   [1]    d = 4 
// By now we know this much :
    d = 4
    b = -d+7
// Use the  d  value to solve for  b 
    b = -(4)+7 = 3 
Solution :
 {d,b} = {4,3} 
 
        
                    
             
        
        
        
Given:

First, let us find two points from this equation.
We can set values of x and then solve for y. 
Let us find the values of y when x = 1, 2, 3, 4, 5

We now have a set of points:
(1, 21)
(2, 16)
(3, 11)
(4, 6)
(5, 1)
Since the given plane is limited to values of 10 and -10, the points that we can plot are the points (4, 6) and (5, 1)
The graph would then look like this:
 
        
             
        
        
        
2.443 x 10^6
Hope it helps! :)
        
             
        
        
        
Given that <span>C = { X | X + 6 = 10}
This can be interpreted grammatically as "C is a set X such that X is the solution to X + 6 = 10".
Given that X + 6 = 10
X = 10 - 6 = 4
Therefore, the solution is
C = {4}
