   Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : 

 X= 49

Answer: x = 49 .
_____________________________________________________
 13-x/7=6 ;  is:  13 - (x/7) = 6 ;  So, 13 - y = 6 ; solve for "y";  y = 7; so;

(x/7) = y = 7 ;  (x/7) = 7;  
                            7 * 7 = x ;  x = 49 .
