How many beads

In a box, (5/8 ) of the beads were red, (1/3) of the remaining beads were green and the rest were blue. After (5/6) of the blue beads and 5 green beads were used, 128 were left. How many beads were there in the box at first?

My work: I couldn't get far, but this is what I got.

Red = r
Green = g
Blue = b


(5/8 )r + (1/8 )(g - 5) + (2/8 )(b - 5/6) = Total - 128

t = total beads

r = 5t/8
g = (t - 5t/8)/3 = t/8
b = t - r - g = 2t/8

t - (5/6)b - 5 = 128
t - (5/6)(2t/8) - 5 = 128

Hope you're not too tired to finish it!
Thanks from xoritos
