Answer 1

Answer:

Step-by-step explanation:

taking 16/7 * 8/7 * 8/7 common :

we get

16/7 * 8/7 * 8/7(4- x/2)=0

sending 16/7 * 8/7 * 8/7 to RHS

4=x/2

x=8

Answer 2

We use DMAS rule to solve the problem:

$\displaystyle\quad\frac{16}{7}\times\frac{16}{7}\times\frac{16}{7}-\frac{x}{2}\times\frac{16}{7}\times\frac{8}{7}\times\frac{8}{7}=0$

$\displaystyle\Rightarrow \bigg(\frac{16}{7}\bigg)^{3}-x\times\bigg(\frac{8}{7}\bigg)^{3}=0$

$\displaystyle\Rightarrow 2^{3}\times \bigg(\frac{8}{7}\bigg)^{3}-x\times \bigg(\frac{8}{7}\bigg)^{3}=0$

$\displaystyle\Rightarrow 2^{3}-x=0$

$\displaystyle\Rightarrow x = 8$

This is the required solution.
