Question

I need help on this...

Answer 1

-5 + 3u = -14
3u = -9
u = -3

Hope this helps :)

Answer 2

To solve for u, you just have to isolate it. Let's take it step by step:

1. Add 5 to both sides to get rid of it on one side:

`-5+5+3u=-14+5`

`3u = -9`

Divide by 3 to get rid of it:

`(3u)/(3) = (-9)/(3)`

`u = -3`

So, we have found the value of u, it is: u = -3
