@asdfghjkl1 that does not explain the difference.
Those two equations have different solutions.

anonymous · Answer

does it say the answer 4 them

anonymous · Answer

Almost, but that's not the point.

anonymous · Answer

the question is asking what is the difference in solving the two equations

anonymous · Answer

Yes, so did you notice first that for the first equation, x is not isolated on the left side and in the second equation it is?

anonymous · Answer

oohhh!. okay thanks :)

anonymous · Answer

And you know that that makes a big difference in what the solutions are, right?
