Answer:
If a number is even is the conditional statement.
Step-by-step explanation:
The phrase that starts with "if" is the hypothesis for conditional statement. The phrase that starts with "then" is conclusion for the statement.
Here, the statement is "If a number is even then it is divisible by 2".
Hypothesis = If a number is even
Conclusion = It is divisible by 2
 
        
             
        
        
        
To simplify this, we first need to distribute the 2 into the parenthesis. 
= 2 * x + 2 * 3 - 4 
Now, we can simplify:
= 2x + 6 - 4
= 2x + 2
Hope this helps!
