Idk how to solve 0=4+n over 5
miv72 [106K]
<span> 0=4+n over 5
In number form the equation is
</span>0= \frac{4+n}5}

<span>We want to isolate n, so to undue division we multiply, we'll multiply each side by 5 Leaving the equation as
</span>0=20+n
<span>
Next we'll subtract 20 from each side to isolate n
The equation would now be
</span>-20=n
<span>
So the answer is N=-20
