$\boxed{x=14}$

Reorder the terms:

$-9 + 2x = 5 + x$

Solving

$-9 + 2x = 5 + x$

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-1x' to each side of the equation.

$-9 + 2x + -1x = 5 + x + -1x$

Combine like terms: $2x + -1x = 1x$

$-9 + 1x = 5 + x + -1x$

Combine like terms: $x + -1x = 0$

$-9 + 1x = 5 + 0\\-9 + 1x = 5$

Add '9' to each side of the equation.

$-9 + 9 + 1x = 5 + 9$

Combine like terms: $-9 + 9 = 0$

$0 + 1x = 5 + 9\\1x = 5 + 9$

Combine like terms: $5 + 9 = 14$

$1x = 14$

Divide each side by '$1$'.

$x = 14$

Simplifying

$x = 14$
