Solve the following equation for x.

ax-b=bx-a

~~~~~~~~~~~~~~~~~





ax - b = bx - a  --->

(ax - bx) + (a-b) = 0  --->

(a-b)x + (a-b) = 0  --->

(a-b)*(x+1) = 0  --->


1)  if a =/= b then x = -1 is the ONLY solution.


2)  if a = b, then ANY value of x IS THE SOLUTION.




Answer.    If  a=/= b  then the only solution is x = -1.





                If  a = b  then any value of  x  is the solution.
