Answer:

x =y= 8

Step-by-step explanation:

y = x

y = 2x – 8

Replace y with x

x = 2x-8

Subtract 2x from each side

x-2x = 2x-8-2x

-x = -8

Multiply each side by -1

x = 8

Now solve for y

y=x

y = 8

Setler [38]

Answer:

$\large\boxed{x=\dfrac{6b}{\pi n^2}}$

Step-by-step explanation:

$b=\dfrac{1}{6}\pi n^2x\qquad\text{multiply both sides by 6}\\\\6b=\pi n^2x\qquad\text{divide both sides by}\ \pi n^2\neq0\\\\\dfrac{6b}{\pi n^2}=b$
