How do you solve this?
2 answers:
Answer and explanation:
<em>To solve this, you must find what x equals</em>
x + 2x + 7 = 3x - 7 <em>Add together any numbers that can be added on their side</em>
3x + 7 = 3x - 7 <em>Then subtract 7 from both sides to get 3x alone</em>
3x = 3x - 14 <em> Then subtract 3x from both sides to get x</em>
<h3><em>*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*</em></h3>
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.
