Step-by-step explanation:
Add -1 to each side.
1+-1+3x-14+-1
Combine the like terms.

Hope this helps. Plz give brainliest.
<h3>3x + 1 = - 14</h3>
- bring 1 over to the other side as it is alike to negative 14
- when you bring 1 to the other side it turns into negative 1
<h3>3x = - 14 - 1</h3>
- subtract negative 1 from negative 14
<h3>3x = - 15</h3>
- bring 3 over to the other side and divide it by 15
<h3>x = - 15 ÷ 3</h3>
<h2>x = - 5</h2>
hope that helps :)
