Originally Posted by lilfreak -4/7a = - 28 Can I assume this is (-4/7)a = -28? Then 7(-4/7)a = 7*(-28) (-4)a = 7*(-28) (-4)a/(-4) = 7*(-28)/(-4) a = 7*(7) = 49 -Dan Or: (-4/7)a = -28 (-7/4)(-4/7)a = (-7/4)(-28) a = -7*(-7) = 49

As my Daddy taught me: Keep It Simple Stupid. It could be that complicated, but odds are it's simple. If not, they'll let me know, I'm sure. -Dan
