how do you solve for x in 4x-1=4x+7?

Question

I'm guessing you're noticing that x's disappear, right?

anonymous · Answer

No solution.

psymon · Answer

Well,he was just here to spit it out. But basically, if you ever get two things that are clearly not equal to each other in something like this, then there is no solutions. On the otherhand, if you get two things on opposite sides that are exactly equal, there are infinite solutions.

whatever the $x$ is on one side, it is the same as the $x$ on the other
and so the $4x$ on the left is equal the $4x$ on the right
it is  not possible to subtract 1 from a number, and get the same answer when you add 7

yes the x's do disappear  so I am assuming there are two answers for x?  how do I find both answers or is there an answer?

anonymous · Answer

This is exactly what I came up with so the answer is "no solution"?
