_______________________________
Explanation:
_______________________________________
Given the following system of equations:
_______________________________________
x + y = 3 ;

y = 9 ;
_________________________________

Substitute "9" for "y" in the first equation; to solve for "x";  we already have our value for "y" ;   "y = 9 " ; (given) ;

____________________________
      x + 9 = 3 ;

Subtract "9" from EACH side of the equation;
_____________________________________
     x + 9 − 9 = 3 − 9 ;

to get:
_____________________________________
         x = -6 .
_____________________________________

Check our  answer:

x + y = 3
________________
-6 + 9 =? 3 ?   Yes!
_____________________
The answer for the system of equations is: 
_____________________________________
     x = -6,  y = 9 ;  or, write as:  (-6, 9) .
