Because the arrow is pointing to the left, the answer to the solution set needs to be less than the the number the dot is on.
A solid dot on a number means that that number is included in the solution set.
In the picture the solid dot is on 4.5, so the solution set needs to be equal to or less than 4.5.
The answer is:
{x | x ≤ 4.5}
 
        
                    
             
        
        
        
26x3=78
78-x=72
x=6
