1+ 8n - 6n = 13 + 6n -6n; 1 - 1 + 2n = 13 - 1; 2÷ 2n = 12 ÷2; n = 6

The answer is n=6

1+8n=13+6n
1+8n=13-6n
-6n
1+2n=13
-1 -1
2n=12
2n divided by 2... 12 divided by 2 = 6... n=6

How do you calculate it? You start by expressing the density in the units you have. Then you multiply by appropriate conversion factors to get to the units you want. Treat units as though they were any other variable. A value cancels that appears in both the numerator and denominator of a fraction.

$\dfrac{56.15\,kg}{0.222\,hh}\cdot \dfrac{1000\,g}{1\,kg}\cdot \dfrac{1\,pw}{1.55\,g}\cdot \dfrac{1\,hh}{238.5\,L}\cdot \dfrac{9.091\,L}{1\,pk}\\\\=\dfrac{56.15\cdot 1000\cdot 9.091\,pw}{0.222\cdot 1.55\cdot 238.5\,pk}\\\\ \approx6220\,\frac{pw}{pk}$

-3(y-5) simplify please

Im pretty sure its 8y because two negatives equal a positive so 5 plus 3 and then you isolated the y so 8y. :)
