Question 805680
<pre>
  1 = 3 + {{{n/8}}}

Add -3 to both sides

  1 = 3 + {{{n/8}}}
 -3  -3
--------------------
 -2 =     {{{n/8}}}

Multiply both sides by 8

-16 = n

To check, substitute (-16) for n in the original
equation:

  1 = 3 + {{{n/8}}}
  1 = 3 + {{{((-16))/8}}}
  1 = 3 + (-2)
  1 = 3 - 2
  1 = 1

BTW, 1=3+(-2) is right but 3+-2=-1 is wrong!
