Here are the choices for it to answer
Complete the proof of the cancellation property of vector addition by justifying each step.
Prove that if u, v, and w are vectors in a vector space V such that u + w = v + w, then u = v.
Step
Justification
u + w = v + w
original equation
(u + w) + (-w) = (v + w) + (-w) --Select---
u + (w + (-w)) = v + (w + (-w))
--Select---
u + 0 = v + 0
Select---
u = v
---Select---
-Select--
the commutative property of addition
add -w to both sides of the equation
the additive inverse property
the additive identity property
