Find the value of $x$ if $ 5 x+2(x+7)=14 x-7 $.

Given:

\( 5 x+2(x+7)=14 x-7 \).

To do:

We have to find the value of $x$.
Solution:
\( 5 x+2(x+7)=14 x-7 \)

$\Rightarrow 5x+2(x)+2(7)=14x-7$

$ \Rightarrow 7x+14=14x-7$

$\Rightarrow 14x-7x=14+7$

$\Rightarrow 7x=21$

$\Rightarrow x=\frac{21}{7}$

$\Rightarrow x=3$

The value of $x$ is $3$.
