What is X Plus - 8 equals 3x plus 6

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
