How would you do this?
Rs=8y
St=4y+8
RT=115y9
a.Find the value of y
b. Find rs, st, rt

RS+ST=RT
8y+4y+8 = 115y9
103y = 17
y = 17/103
now plug that into the expressions for the segments 
How'd you get that? I was trying the problem and couldn't get it

I'm sorry rt=15 not 115

I got y=17 Am I right?

well, let's see:
8y+4y+8 = 15y9
3y = 17
y = 17/3
right off, you should have realized that a negative value for y makes no sense, since we are dealing with line segments, which have positive lengths.
I'm still bothered by the fraction answer. A simple exercise like this usually has a nice integer result.
