Hey there!
2(6 * 4) + 2(6 * 2.4n) + 2(4 * 2.4n)
= 2(24) + 2(14.4n) + 2(9.6n)
= 48 + 28.8n + 19.2n
= 48 + 48n
= 48n + 48
Thus, your answer should be: 48n
Good luck on your assignment and enjoy your day!

Answer:
10(10+x)
Step-by-step explanation:
First you'd substitute x= y-3 in the first equation.
10(y-3) -10y= 1
10y - 30 -10y= 1
The y's cancel each other out, so you're left with -30= 1. That means there's no solution :)
