The following code works in version 2.8.13 of SAGE:
a = (16*x - 13)/6 == (3*x + 5)/2 - (4 - x)/3
But when I execute it in version 2.9, the following error is generated:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/tkosan/.sage/sage_notebook/worksheets/admin/0/code/7.py",
line 4, in <module>
a = (Integer(16)*x - Integer(13))/Integer(6) == (Integer(3)*x +
Integer(5))/Integer(2) - (Integer(4) - x)/Integer(3)

TypeError: unsupported operand parent(s) for '-': '<type 'list'>' and

Any thoughts?
