Answers:
16. 6-x= 10
move +6 to the other side 
sign changes from +6 to -6
6-6-x= 10-6
-x= 4 
Mutiply both sides by -1 
(-1)(-x)= (-1)(4)
x= -4
17. 4a+3= -9
move +3 to the other side 
sign changes from +3 to -3
4a+3-3= -9-3 
4a= -12 
divide both sides by 4
4a/4= -12/4
a= -3
 
        
                    
             
        
        
        
Answer:
See below
Step-by-step explanation:
Start by subtracting 5.2 from both sides of the equation
   so  "subtraction property of equality "    I suppose ......
then the next step would be divide both sides by 2.5  
   which would be division property of equality  
 
        
                    
             
        
        
        
Answer:
 <em>(1, 7) </em>
Step-by-step explanation:
y = 3x + 4
y = 6x + 1 
6x + 1 = 3x + 4 ⇒ x = 1 
y = 3(1) + 4 = 7 
<em>(1, 7)</em> 
 
        
                    
             
        
        
        
This basically means that you have to multiply the x and y values by 3. So 2 time 3 is 6. And -7 times 3 is -21. So the new coordinations are (6, -21)
Hope this helped and pls mark as brainliest!
