Answer:
Any real number
Step-by-step explanation:
Let your no.= x
double the number=2x
add 4 = 2x+4
subtract same number=2x+4-x
subtract 3=2x+4-x-3
get number plus 1=x+1
  
so equation we get
2x+4-x-3=x+1
x+1=x+1
  
x=x
  
it means  x is equal to all real number
So your number can be any real number

Answer:
17
Step-by-step explanation:
The discount on the shirt is 15%
Discount = price* discount rate
                = 20 * 15%
                = 20 * .15
                 =3
The new price is the previous price minus the discount
new price = 20-3
new price = 17
 
        
                    
             
        
        
        
A = x > -3 and x < 4
B = x >withlineunder -3 and x <withlineunder 4
C = X < - 3 or X > 4
