Proving v=w using Vector Space Axioms

Click For Summary
SUMMARY

The discussion centers on proving the equality v = w within an arbitrary vector space V, given the equation v + x = w + x, where v, w, and x are elements of V. Participants clarify the initial statement and confirm the use of vector space axioms, particularly focusing on the additive inverse and the zero vector. The conclusion emphasizes the necessity of applying the axioms correctly to manipulate the equation and derive the desired result.

PREREQUISITES
  • Understanding of vector space axioms
  • Familiarity with additive inverses in vector spaces

Homework Statement



V is an arbitrary vector space and v,w,x are part of V such that v + x = w = x

Use vector space axioms to prove v = w

I've looked at the axioms for an hour and can not get any lead to start this question.
 
Physics news on Phys.org
You mean [itex]v + x = w + x[/itex] right?

Well, [itex]x \in V[/itex], right? Doesn't it have an additive inverse?
 
yeah it satifies the 10 vector axioms, but i can't seem to muck around with the axioms to solve the problem.

Yeah sorry i meant v + x = w + x

I know it has something to do with the 0 vector. ie 0 = +x -x

When i incorporate that into the eqn i get v +x -x +x = w +x -x +x ... which I am not sure if it helps
