Answer:
[tex]n=\frac{a}{m-b}[/tex]
Step-by-step explanation:
So we have the equation:
[tex]nm=a+nb[/tex]
Let's isolate n. To do so, subtract nb from both sides:
[tex]nm-nb=a[/tex]
On the left, factor out an n:
[tex]n(m-b)=a[/tex]
Divide both sides by (m-b):
[tex]n=\frac{a}{m-b}[/tex]
And we're done!
