Answer:
x=165
Step-by-step explanation:
Multiply both sides by 15
15(x/15)=11*15
x=165
 
        
             
        
        
        
Answer:
yessirrr cuz ion kno the answer to this question
..
 
        
             
        
        
        
Slope = (10-1)/(1+2) = 9/3 = 3
y = mx + b
1 = 3(-2) +b
1 = -6 + b
b = 7
equation
y = 3x + 7  
or 
3x - y = -7
answer is <span>3x − y = −7 (first choice)</span>
        
                    
             
        
        
        
There is only one answer, x=7
        
                    
             
        
        
        
You just have to add one eqaution to another :
-x + x -y + 2y = 7 + 7
y = 14 
Then apply y = 14 to one of the equations :
eg: x + 2(14) = 7
x + 28 = 7
x = - 21
 The awnser is x= -21 y= 14
I hope i awnsered your question
