我想你大概有两个问题.
一是关于same的搭配问题,它的常用搭配是“the same...as...",一般是不用with的.
二是as后面是用人称的主格还是名词性物主代词.这取决于句中所比较的主体是谁.具体来说吧,
1.i am the same age as you.
2.i am of the same age as yours.
第一句中,比较的主体是"i" 和"you",相当于"you"省略了"are",意思是“我和你一样,有相同的年龄”；而第二句中因为有了"of",所以比较的主体转化到"age",比较的是“my age”和“your age”(yours),意思是“我的年龄与你的年龄相同”.当然要不那么讲究的话,大概可翻译成同样的意思.
那么后面的句子也是同理.i am the same weight as you.或者i have the same weight as yours.
不知你可否理解?

I am of the same age as you.
I have the same pen as yours.
I am the same age / weight as you
I have an same weight as .
