Posted by min on Wednesday, November 14, 2007 at 7:52pm.

i have this problem, I'm stuck on.

it says find 2 consecutive multiples of 9 whose sum is -153.

I started of my saying the 1st number is 9x and the 2nd is 9x+9.

I continued on to get, 9x+(9x+9)=-153 and solved it.

I got an irrelevant answer: -9.

I was wondering what I had done wrong.
thank you.
