Answer:

x does equal -5

Step-by-step explanation:

Add -1 to each side.

1+-1+3x-14+-1

Combine the like terms.

0+3x=-14+-1

3x=-14+-1

3x=-15

Divide that by 3.

x= -5

<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>

  • this is the answer ...

<h2>x = - 5</h2>

hope that helps :)
