Question

What is the reason for each step in the solution of the equation? 3x-2=4

Answer 1

First you can add 2 on both sides to eliminate the 2 and you end up with 3x=6,so you divide each side by 3,and get x=2

Answer 2

You have to get the X by its self
 then then you would have to add the 2 which would cancel out out on the left 
you would then have to add the 2 to  the 4 which would give you 6
RULE-(what you do on one side you do to the other)
so then your equation would be 3X=6
then you would divide by 3 on both sided which would cancle out the 3 and on the other side of the equal sign you divide by 3 which would leave you with 2 
so then your answer would be-
 x=2
