Answer and explanation:

To solve this, you must find what x equals

x + 2x + 7 = 3x - 7 Add together any numbers that can be added on their side

3x + 7 = 3x - 7  Then subtract 7 from both sides to get 3x alone

3x = 3x - 14 Then subtract 3x from both sides to get x

*The x's cancel each other out so you must have typed the equation wrong. Please check to see any mistakes you may have made*

Well first things first, you need to add like terms. So now you should have 3x+7 =3x-7. Now already looking at this, i know that there is no answer because the two 3x will cancel out, making the equation into 14=0.
