Solve for x first
-6x - 42 = -4x -2
-6x = -4x + 40
- 2x = 40
X = -20
The equation has one solution

Answer:
A
All real numbers
Step-by-step explanation:
Given in the question a graph
To find the range of graph
The range is the set of possible output values, which are shown on the y-axis.
We can see in the graph that for negative values of x it have positive values, zero and negative values of y.
The graph extends vertically from (-∞,∞), along the y axis. So the range of the function shown in the graph is (-∞,∞).  
Hence, it is concluded that range is All real numbers
 
        
             
        
        
        
You have it correct the answer is 20
        
             
        
        
        
The answer is D) All the steps and the answer are correct. :) 
You can just solve using the steps to see if they are right. For example, is -1x17=-17? Yes.
