x - 3y = -3 ;

x + 3y = 9;

(x - 3y = -3) + (x + 3y = 9) ;

2x = 6 ;

x = 6/2 ;

x = 3 ;

3 - 3y = -3 ;

-3y = -3 - 3 ;

-3y = -6 ;

y = -6/-3 ;

y = 2 ;

Solution set: (3, 2)

x + 3y = 9;

(x - 3y = -3) + (x + 3y = 9) ;

2x = 6 ;

x = 6/2 ;

x = 3 ;

3 - 3y = -3 ;

-3y = -3 - 3 ;

-3y = -6 ;

y = -6/-3 ;

y = 2 ;

Solution set: (3, 2)
