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
