7x + 24 = - 21

I dont understand what im doing wrong!!! -

ok, so you want to get the numbers on one side, and the x's on the other -

subtract 24 from both sides, so you get
7x = -45

divide -45 by 7, and you get the wrong answer!!!!!

Not sure if the answer should be in mph, or meters per second, whatever answer you feel is best, thanks.

1. Set S and a binary operation * on S will be specified. In each case, determine whether * is associative, whether * has an identity element and, if the latter is the case, whether each element of S has an inverse (with regard to *), i.e whether S is a group:
(a) S=3Z, the set of all integers that are multiples of 3, * = ordinary addition of integers
(b) S=Z, a*b=a+b-1

2. A table defines a binary operation * on the set S={a,b,c,d}. Is (s,*) a group? If not why?

If someone could please give me full working out and explinations I would really appreciate it.

Thanks

Don

did you memorize the answer?? It's -(x+1)

[x^2 -1]/(1-x) can't really be simplified by anything that I leanred and I am in calculus now ...so I just used synthetic division ...and I got -(x+1) ...but should I memorize this ...do most people memorize this solution ...or no?
