Question

I'm trying to solve a equation of 3x-2=1 In the book, it says that 3 -2=-1 turns into 3x=3. I don't get it?! Shouldn't it be 3x=-1?

Answer 1

Answer: The answer should be 3x = 3.

Explanation:

Here's why:

3x -2 = 1

First one must isolate the 3x in order to solve the problem. So, then one must add 2 to both sides, since the 2 is negative. (So if it is a -2, add it to the other side because remember, you are doing it on both sides and you have to get it to the other side).

So doing that, you get:

3x = +2 +1

3x = 3

If you want to simplify further:

3x = 3

x = 1

Answer 2

Answer: The book is right, it would break down to 3x = 3.

3x - 2 = 1 so add the 2 to the other side.

3x = 3 and then you can divide both sides by 3 to get x = 1.

Sorry if I misread what you were asking
