The associative property is used when you group different numbers in the same problem and its still the same. only with adding and multiplying.

(2+3)+4=2+(3+4)

The commutative property is when you change the order of the numbers in the same problem and its still the same. Only with adding and multiplying.

2+3+4=3+2+4

10/2/08     I DID THE WRONG PAGE!!!!! I did 118 1) x - 8 = 0   x=8    8-8=0 2) c-4=9   c=13   13-4=9 3)-4=2/5a    a=1   3/5    -4=2/5 * 3/5 4)-8n=-64     n=8    -8(8)=-64

5) b+5=-13   b=-18     -18+5=-13 6) 6=x+2    x=4   6=4+2 7) -7y=28  y=-7    -7(-7)=28 8)-101= -r/3 r=303 -101= -303/3

9) 67=w-65   w=131    67=131-65

10/3/08 40) 8 + c/-4 = -6    c/-4 = -14    c=56 41) 7 - 3k = -14        -3k = -21     k=7

42) 14 = 6 - 2p        8 = -2p           p=-4

43)-y/2 + 14 = -1    -y/2=-15     y=30

10/6/08 5) 4x + 3 = -5  x=-2   6) x + 7= 12      x= -5 7) 2t-8t+1=43 t= -7 8) 0=-7n+4-5n n= 1/3 29)1/5 + 3w/15=4/5   w=3
