x+2=3x+8
Subtract 3x from both sides
x+2
−
3x
=
3x
+8
−
3x
−
2x
+2
=
8
Subtract 2 from both sides
-2x+2-2=8-2
-2x=6
Then divide both sides by -2

x + 2 = 3x + 8
(Subtract 8 over)
x - 6 = 3x
(Commutative property, x on the left is easier to understand usually)
3x = x - 6
(Subtract x over)
2x = 6
(Divide both sides by 2)
x = 3
