$d = 4n -2 \\d + 2 = 4n\\\frac{1}{4}d + \frac{2}{4} = n\\\\n = 0.25d + 0.5$

For a 3-penny nail
$n = 0.25d + 0.5\\ n = 0.25(3) + 0.5\\n = 0.75 +0.5\\\\n = 1.25$

For a 6-penny nail
$n = 0.25d + 0.5\\n = 0.25(6) + 0.5\\n = 1.5 + 0.5\\\\n = 2$

For a 10-penny nail
$n = 0.25d + 0.5\\n = 0.25(10) + 0.5\\n = 2.5 + 0.5\\\\n = 3$

Hope that helped :)

Answer:

Step-by-step explanation:o

x + y = 10........(1)

2x = 24

x = 24/2

x = 12

And x + y = 10.......(1)

12 + y = 10

y = 10 - 12
