X=-3 and y=5
2x+y=-1

-x+3y=18
3y-18=x

2(3y-18)+y=-1
6y-36+y=-1
7y=-1+36
7y=35
y=35/7
y=5

-x+3y=18
-x+3(5)=18
-x+15=18
-x=18-15
-x=3
x=-3

The ratio of men to women in a room is 3:4. Eight women enter the room, no men enter the room and none of the original people in
vampirchik [111]
There are 64 people in the room.

Since the ratio for women increases 1 when 8 women enter the room, for every time there is 1 in the ratio there are 8 people. That means that originally you have to do 3x8 and 4x8. You get 24 and 32 which equals 56. Then when 8 more women enter the room, you get 64.
