Question 368967
2x+4=3x-2   Subtract 2x from both sides.
4=x-2       Add 2 to both sides.
6=x   So, x=6.

4-2x=3x-2   Add 2x to both sides.
4=5x-2     Add 2 to both sides.
6=5x     Divide both sides by 5.
6/5 = x   So, x=6/5.


Basically, you are trying to get x by itself.  The rule is anything you do to one side you have to do to the other, whether it be adding or subtracting a number or multiplying or dividing a number.  
Good Luck!
