**msp**, Tuesday, March 18, 2008 at 10:12amBreak it down according to what you know, then you will be able to figure it out. Here is what we know. A good base will be blue, since there is much based off of it.

x = blue

5x = red

3x = green

x + 9 = black

x + 2 = purple

6 = white

You know purple is 5, so figure out x, then you can do the rest.

**Reiny**, Tuesday, March 18, 2008 at 10:13amRed = 5Blue

Green = 3Blue

Black = Blue + 9

Purple = Black - 7

Purple = Blue + 9 - 7

Purple = Blue + 2

But Purple = 5

Blue + 2 = 5

Blue = 3

then Red = 15

Green = 9

Black = 11

Black = 4

Purple = 5

White = 6

check: 15+9+11+4+5+6 = 50
