Well I need more details for x can you screenshot? It’s usually x*0.20 but I need more details to help you
        
             
        
        
        
y=−3x+9 slope of this equation is -3 and y-intercept is 9
Plot the y -intercept first which is 9 and mark the points using the slope which is -3. Join the points. So blue line in the graph is y = -3x+9
y=−x−5 slope of this equation is -1 and y intercept is -5
Plot the y -intercept first which is -5 and mark the points using the slope which is -1 . Join the points. So pink line in the graph is y = -x-5
The intersection point of these two lines gives you the solution. 
The coordinates of point of intersection (7,-12)
 
        
                    
             
        
        
        
 
Reflexive Property=For all real number X,X=X
 A number equals itself
Addition Property=For all real number X,y & Z,. if 
 X=Y then X+y=y+Z 
Subtraction Property=For all real number X,Y And Z if X=y then X-Z=y-Z.
