Answer 1

x=4

Explanation:

1. -3x - 8 = - 20
2. -3x = -20 + 8
3. -3x = -12
4. x=-12/-3
5. x = 4

Answer 2

x=4

Explanation:

I don't really know what you mean by how you would write this, but I can help you solve it!

-3x -8 = -20

We can multiply both sides by -1 which gives us:

3x + 8 = 20

Then we subtract 8 from both sides:

3x + 8 - 8 = 20 - 8

3x = 12

Finally, we divide both sides by 3:

3x/3 = 12/3

x = 4

You can write down the work as I did above, just without the sentences. Let me know if you have any questions!
