N=5
Since 6n and 3n have the same variables you need to subtract them. So 6n-3n=3n. Now you have 3n=15. To get n by it’s self you need to divide 3 by 15. 3 divided by 15 is 5. This means that n=5. Hope this helps!!

The formula to find a circle's area π (radius)2 usually expressed as π⋅r2 where r is the radius of a circle. The area of a circle is all the space inside a circle's circumference.
Step-by-step explanation:
Answer:
X=9 and Y=81
Step-by-step explanation:
Just move all terms to the left side and set equal to zero. Then, set each factor equal to zero.
a = 5,1
Chris is twice as old as Bradley: C = 2B
Devin is eight years older than Bradley: D = B + 8
Mitchell is eight years older than Devin: M = B + 8 + 8
Bradley: B = B
Plug in the values:
-->
Subtract 24 from both sides.
5B = 104 - 24
5B = 80
B =
B = 16
Plug in the values to know the age of each player:
Chris: 2(16) Chris is 32 years old.
Devin: (16) + 8 Devin is 24 years old.
Mitchell: (16) + 8 + 8 Mitchell is 32 years old.
Bradley is sixteen years old.
To check your work, add up all of their ages: 2(32) + 24 + 16 = 104
