x + -8 = 3x + 6
x - 8 = 3x + 6
(x - 8) + 8 = 3x + 6 + 8
x = 3x + 14
x - 3x = (3x + 14) - 3x
-2x = 14
2x = -14
x = -7

x=7      this is how you  do it you just combine like terms but there isn't so you just add 8 to both sides so it would be x=3x+14 then you would subtract 3x to both side and it would be -2x=14 then divide by 2 not negative two and get x=7 because you can't have something equal negative x
