Question

Fill in the blank for the following two-column proof.
Given: 3x+1=-14 Prove: x=-5

Answer 1

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

Hope this helps. Plz give brainliest.

Answer 2

3x + 1 = - 14

• 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

3x = - 14 - 1

• subtract negative 1 from negative 14

3x = - 15

• bring 3 over to the other side and divide it by 15

x = - 15 ÷ 3

• this is the answer ...

x = - 5

hope that helps :)
