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
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.
