-4 and -15
2007-04-04 17:01:52 · answer #1 · answered by Kikka 2 · 0⤊ 0⤋
Solution in steps goes like this:
first, find factors of 60 (numbers multiplying to 60)
1&60, 2&30, 3&20, 4&15, 5&12, 6&10.
Which of these numbers adds to 19?
4&15
the signs have to match up, though, so they're both really negative
60 = -4 * -15
-19 = -4 + -15
Hope this helps!

Assuming you will need to show your work...
xy=60 and x+y=-19 (Thus x=-y-19)
Substute for x so..
(-y-19)*y=60
-y2-19y=60
-y2-19y-60=0
Factor:
(y+4)(-y-15)=0
y+4=0 and -y-15=0
y=-4 and y=-15
