Answer:
-3
Step-by-step explanation:
Let x equal the mystery number
Our equation will be:
x - 5 = 1 + 3x
Subtract x from both sides
-5 = 1 + 2x
Subtract 1 from both sides
-6  = 2x
Divide both sides by 2
-3 = x
 
        
             
        
        
        
It would be 5 more than half of a number.
