Question 106687
6x + 4(3x – 2) = 6x + 2  

is it then {{{6x+12x-8=6x+2}}}   ..yes, it is
then {{{18x-8=6x+2}}} ...........yes, it is. Now add {{{-6x}}} to both sides
  
{{{x=-2 }}} this is not ok !

 you have to do it this way:

{{{18x - (6x) - (8)= 6x - (6x) + 2}}}

{{{12x - (8) = 2}}}......add {{{+8}}} to both sides

{{{12x + 8 - (8) = 2 + 8}}}

{{{12x = 10}}}..divide both sides by {{{2}}}

{{{6x = 5}}}

{{{x = 5/6}}}
