3x + 1 = 2x – 3 Why can't you add 3x with 2x? And what should you do for the first step
Instead.

Answer :

Answer:

You can’t add 3x with 2x because to get term to the other side of the equal sign, you need to do the inverse (opposite) of the number. Since 3x is positive (basically with a + in the front) you SUBTRACT 3x for it to get to the other side. Which will get u -1x or just -x.
