Given:

\( 5 x+9=5+3 x \).

To do:
 We have to solve the given equation and check the result.

Solution:

$5x+9=5+3x$

$5x-3x=5-9$

$2x=-4$

$x=\frac{-4}{2}$

$x=-2$

Substituting the value of $x$ in LHS, we get,

$5x+9=5(-2)+9$

$=-10+9$

$=-1$

Substituting the value of $x$ in RHS, we get,

$5+3x=5+3(-2)$

$=5-6$

$=-1$

LHS $=$ RHS

The value of $x$ is $-2$.
