Answer 1

Olá! (^_-)

-----

${ \large \displaystyle \sf {6x + 9 + 3x = 18}}$

${ \large \displaystyle \sf {9x + 9 = 18}}$

${ \large \displaystyle \sf {9x = 18 - 9}}$

${ \large \displaystyle \sf {9x =9}}$

${ \large \displaystyle \sf {x = \frac{9}{9} }}$

$\boxed{ \boxed{ \red{{ \large \displaystyle \sf {x =1}}}}}$
