answer:

<em>x  = 14</em>

explanation:

7x - 1 + 6x - 1 = 180

( group like terms )

7x + 6x - 1 - 1 = 180

( add like terms: 7x + 6x = 13x )

13x - 1 - 1 = 180

( subtract whole numbers: -1 - 1 = -2 )

13x - 2 = 180

( add 2 to both sides )

13x - 2 + 2 = 180 + 2

( simplify )

13x = 182

( divide both sides by 13 )

13x / 13 = 182 / 13

( simplify )

<em>x  = 14</em>

This is crazy.  If I'm reading this right (I'm not sure why there are spaces put in between some of those numbers like there is), I'm getting that the answer is
-1079.242293.  But again, those spaces are throwing me off.  I eliminated the spaces between the numbers while I was performing the operations in order.
