Based on the given information, can you conclude that (triangle) qrs is congruent to (triangle) tuv? explain.
given: qr is congruent to tu
qs is congruent to tv
angle r is congruent to angle u
qrs is congruent to tuv

For the answer to the question above,
QS = 3x = 2 
Did you mean QS = 3x-2 ? Spelling error ? 

If triangle QRS is congruent to triangle TUV 
TV is congruent to QS 
3x-2 = 7x-6 
-4x=-4 
x=1
I solved it just to be complete. But the  answer for your question is the second one among the given choices which is QS is congruent to TV
