Answer:

n = [tex]\frac{5}{7}[/tex]

Step-by-step explanation:

Given

21n = 15 ( divide both sides by 21 )

n = [tex]\frac{15}{21}[/tex] ← divide ( cancel) 15 and 21 by 3, thus

n = [tex]\frac{5}{7}[/tex]

Hi there!

~ Solving: 21n=15

In this case, "n" is already by itself. Therefore we divide "21" by each side!

21n/21 = 15/21

When simplified, you get 5/7.

Therefore, our answer is 5/7.
