Answer 1

Hello!!!

$10x + 5x + 5x + x = 8400$

$\to \: 21x = 8400$

$\to \: x = \frac{8400}{21}$

$\to \: x = 400$

∴ Hence, the value of $ x $ will be 400.

Answer 2

Step-by-step explanation:

$10x + 5x + 5x + x = 8400 \\ 15x + 5x + x = 8400 \\ 20x + x = 8400 \\ 21 x = 8400 \\ x = \frac{8400}{21} \\ x = 400$
