# x-6>=0#

Explanation:

The first step is to put everything that #x# multiplies in the same side of the equation:
#x/3 >= 1 + x/6# becomes #x/3 - x/6 >= 1#.

Then, you make everything have the same denominator:
#x/3 - x/6 >= 1# becomes # (2x)/6 - x/6 >= 1#.

#(2x)/6 - x/6# can be expressed as #(2x - x)/6#, so:

#(2x - x)/6 >= 1#. We know that #2x - x = x#, so:
#x/6 >= 1#. Making everything have the same denominator, we have:
#x >= 6#, and so # x-6>=0#
