Answer:
Step-by-step explanation:
the solution to the system
= find the intersection of two lines
method( one )
solve the equations ( find(x , y) )
( 1 ) y = -x +3
( 2 ) y = x - 3
now , we let ( 1 ) + (2 )
we have 2y =0 ,thus y = 0
from ( 1 ) y = - x +3 , we know y = 0 ,
we rewrite ( 1 ) as 0 = -x + 3,thus x = 3
method( two)
see the intersection point of two lines
so the ans is B.(3 , 0)
