Answer:
[tex] \displaystyle \large \boxed{ n = \frac{k - 13}{y} } \\ \displaystyle \large \boxed{ n = \frac{k}{y} - \frac{13}{y } }[/tex]
Both solutions work!
Step-by-step explanation:
We are given the equation:
[tex] \displaystyle \large{yn + 13 = k}[/tex]
To solve or isolate the n-term — first, we subtract 13 both sides.
[tex] \displaystyle \large{yn + 13 - 13 = k - 13} \\ \displaystyle \large{yn = k - 13}[/tex]
Since we want to isolate n-term, we divide both sides by y-term.
[tex] \displaystyle \large{ \frac{yn}{y} = \frac{k - 13}{y} } \\ \displaystyle \large{ n = \frac{k - 13}{y} }[/tex]
Alternate Solution
The answer above is correct, but for this alternate solution, we will simplify or separate the fraction.
From the equation n-isolated:
[tex] \displaystyle \large{ n = \frac{k - 13}{y} } \\ \displaystyle \large{ n = \frac{k}{y} - \frac{13}{y } }[/tex]
