7. in which quadrant does the solution of the system fall?
x + y = 4
2x – y = 2

a. i
b. ii
c. iii
d. iv

From X + Y = 4 
Y = 4 - X 
Substituite this for Y in 2X - Y = 2 to get 
2X -(4 - X ) = 2 
2X -4 +X = 2 
3X = 6 
X = 2 
Now return to X + Y = 4 
Knowing X = 2, 
2 + Y = 4 
Y = 4 - 2 
Y = 2 
The solution is (X,Y) = (2,2) 
This is quadrant I 
Answer is A

The answer would he -4,-2 because the points are just on the opposite side. since the x axis is +4 it's going to he -4 and since the y axis is -2 it stays there because whaen rotated it stays in the third quadrant
