Answer 1

why do you duplicate everything? And then do it again in words!? Very annoying!
First step, simplify the equation. For example,
52x+52=52x-78
52 = -78
Nope, no solutions there

Do the others. If your equation reduces to something that is false, there are no solutions. If it turns out always true, then there are infinitely many solutions.

Come back if you get stuck.
