What is the value of
2t+t-x
-------
t-x
1) 2t / (t-x) = 3
2) t-x=5


do you mean "What is the value of (2t+t-x)/(t-x)?"

Elementary. The expression reduces to [2t/(t-x) + 1].

From II, you get the value of (t-x) but not (2t). So it is of no use to us.
From I, you get the value (3+1) = 4.

So ans is A.

What is the value of (2t + t - x)/(t - x)?

\frac{2t + t - x}{t - x}=\frac{2t}{t - x}+\frac{t - x}{t - x}=\frac{2t}{t - x}+1=?

(1) 2t/(t - x) = 3 --> \frac{2t}{t - x}+1=3+1=4. Sufficient.

(2) t - x = 5 --> \frac{2t + (t - x)}{(t - x)}=\frac{2t + 5}{5} --> different values of t will give different values ofr this expression. Not sufficient.

Answer: A.
