**Henry**, Tuesday, September 20, 2011 at 6:25amX = the total # of t-shirts.

3x/7 = the # of red t-shirts.

x/3 = the # of blue t-shirts.

(3x/7-20)=The # of blue t-shirts,also.

x/3 = 3x/7 - 20,

x/3 - 3x/7 = -20,

Multiply both sides by 21:

7x - 9x = -420,

-2x = -420,

X = 210.

3x/7 = 3*210 / 7 = 90 Red t-shirts.

x/3 = 210 / 3 = 70 Blue t-shirts.

Y = 210 - 90 - 70 = 50 Yellow t-shirts.
