X+5y=-11 (1)
2x-3y=17 (2)
2(1)-(2)
2x+10y-2x+3y=-22-17
13y=-39
y=-3
Sub y=-3 in (1)
x+5(-3)=-11
x=4
So x+y= -3+4 =1
Why is the point (4, 3) there but not mentioned??
Anyways, the point that P (3, 0) is after rotating 180° about the origin is (-3, 0).
btw, for 180 rotations about O, just take negative value of (x, y)--> (-x, -y)
That way -(3), -(0) becomes (-3, 0)
True because 6 multiplied by 3 is 18. Therefore, when you divide 18 by 6 the anwser will be 3.
