Answer: -6/11
-4x - 2(8x + 1) = -(-2x - 10)               Distributive Property
-4x - 16x - 2 = 2x + 10                     Combine like terms
-20x - 2 = 2x + 10                           Subtract 2x from both sides
-22x - 2 = 10                                   Add 2 to both sides
-22x = 12                                         Divide by -22 for both sides
x = -6/11                                           Answer!
