Answer:
-2.4 
Step-by-step explanation:
Let the unknown number be x. 
-3.7 = -1.3(1) + x
-3.7 = -1.3 + x
x - 1.3 = -3.7 
x = -3.7 + 1.3 
x = -2.4 
 
        
                    
             
        
        
        
Answer:
A. y = -16
Step-by-step explanation:
Hello!
What we do to one side of the equation we have to do to the other.
y + 7 = -9
We have to get y by itself so we have to get rid of the seven by doing the opposite of what it says
The opposite of addition is subtraction so we subtract 7 from both sides
y + 7 - 7 = -9 - 7
Solve
y + 0 = -16
Simplify
y = -16
The answer is A. y = -16
Hope this helps!
 
        
             
        
        
        
x^2 - 49 = 0
Add 49 to both sides:
x^2 = 49
Take the square root of both sides:
X = 7
