Of course the two numbers are not strictly equal. You can tell that just by looking at them. You just don't have enough precision in the calculations to see the difference.

By default, the symbolic processor uses 20 digits of precision for floating point calculations. You can change that by using the float keyword (which does not just change the precision of the displayed result; it changes the precision used in the calculations).

Assuming that all those digits in the starting equation are actually valid, you are better off using the symbolic processor to solve it. It's more accurate.
