I dont understand the explanation in the book:

If R=2S and S=T-3, then R=2(T-3).
By substitution, therefore:

R>T if and only if 2(T-3)>T ---> how do they come to this conclusion?

Thanks,

Moses

Hi Moses,
I moved this post to the Manhattan GMAT Strategy Guide folder, where I believe it goes. Please specify which book and page you are refering to. (See the Forum Guidelines for a reminder of our posting procedures.)
Thanks,
Emily
