The second, if you try to solve for the variable, you will end up with a false statement, 3=1 or something like that

anonymous · Answer

okay thanks! do you know anything about the first one because I'm not sure what identity is?

danjs · Answer

the opposite,  if you solve and get a true statement,  like   3=3,  then there is no limit to the value of the variable , it will always be true

10p-6-p.........
This one is identity.

danjs · Answer

nah, watch the negative times negative on the distribution

anonymous · Answer

for the identity equation, would it be the first option? or did I mess up with using negatives?

danjs · Answer

the first goes to 
7 - 9x - 3 = -9x - 4    or False,   4=-4 , not identity

danjs · Answer

none of em are, maybe a mistype on a sign

anonymous · Answer

ohhh sorry its 10p+6 not -6
