find what x stands for and then place it in set builder notation

                                       (6/7)x - (1/7)  <=  x - 2

Multiply all terms by 7:               6x - 1  <=  6x - 12

Subtract 6x from both sides:           -1  <=  -12

This is an impossible situation; there is no answer.     The answer set is empty:  { }
