Resposta:

$\color{blue}{\boxed{\boxed{\boxed{\mathsf{\color{red}{x > -30}}}}}}$

Explicação passo-a-passo:

$\mathsf{- 6-12 + 5x < 3(2x + 4)}$

$\mathsf{-18 +5x < 6x +12}$

$\mathsf{-18 +5x -6x < 12}$

$\mathsf{-18-x <12}$

$\mathsf{-x < 12 + 18}$

$\mathsf{-x < 30 \cdot (-1)}$

$\boxed{\mathsf{x > -30}}$
