6 - x = 2 - (9 - 2x)

6 - x = 2 + (-9 + 2x)  Change the sign of each term of the subtrahend
                                  (9 - 2x) then proceed to addition rule

6 - x = 2 - 9 + 2x

6 - x  = -7 + 2x

6 + 7 - x + x = - 7 + 7 + 2x + x   (Applying the Addition Property of Equality)

13 = 3x 

13/3 = 3x/3

x = 13/3    or   4  \frac{1}{3}
