Why do you say that?
Because Given is always the first step.
ok so a.1=a what do u call this property ?
yep exactly :)
but there is one thing that confuse me in ur question, about this one Symmetric Property of Equality i dont see why its wrong to use it, maybe cause its the same property that u wanna prove ?
Im not sure. Its what confused me too...
The answer is Symmetric Property because the basic rule for that one is a=b so b=a In the problem though we're only shown one-half of the property. Both sides are still equal though due to the given.
Okay, I wasnt sure what it would be. That makes sense though. Thank you, both of you
well thats depend on the axiom system ur working on the question itself wanna u to prove if Symmetric Property of Equality really works ,i'll tell u why :- if the reason was symmetric property then why didnt we use it directly to prove a.c=b.c ? got it now ??
Yeah, I get it. Makes way more sense
so the answer is the identity look for how it make more sense
Oh wait- so its Identity not Symmetry?
I see what you're saying, but the reason I went with symmetric was because of the fact that given is the reason fro a*c=b*c
Im confused now.
well here what i think :- 1.ac=bc given 2.ac.1/c=bc.1/c symmetric property (we can multiply both side with same stuff like a balance) 3. 4. 5. 6. identity XD if we use symmetric directly on 6,then there is no need for this whole proof as we can also say ac=bc given a=b symmetric blah blah .. end .
That is true, but I think it is because there is a better fit for the others. Even if it makes it all unnecessary.
Like you said it fits better for 2 but that one actually would be the multiplicative identity.
Yeah, I will go with what I think is best. Then I will let you too know. Thanks so much for the help.
Ahhhh...... The answer was identity. I went with symmetry and got it wrong.
Lol yup. Thanks for the help anyways
no problem :)
