Question

Idk how to solve 0=4+n over 5

Answer 1

 0=4+n over 5
In number form the equation is
$0= \frac{4+n}5}$

We want to isolate n, so to undue division we multiply, we'll multiply each side by 5 Leaving the equation as
$0=20+n$

Next we'll subtract 20 from each side to isolate n
The equation would now be
$-20=n$

So the answer is N=-20
