Explicação passo-a-passo:

$\mathsf{x + 6 = 18}$

$\mathsf{x = 18 - 6}$

$\boxed{\boxed{\mathsf{x = 12}}}$

$\mathsf{3x - 15 = 0}$

$\mathsf{3x = 15}$

$\boxed{\boxed{\mathsf{x = 5}}}$

$\mathsf{7x - 2 + 4 = 14 - 5x}$

$\mathsf{7x + 5x = 14 + 2 - 4}$

$\mathsf{12x = 12}$

$\boxed{\boxed{\mathsf{x = 1}}}$

$\mathsf{4(x + 3) = 0}$

$\mathsf{4x + 12 = 0}$

$\mathsf{4x= -12}$

$\boxed{\boxed{\mathsf{x= -3}}}$

$\mathsf{3(2x - 1) = -4x + 3}$

$\mathsf{6x - 3 = -4x + 3}$

$\mathsf{6x + 4x = 3 + 3}$

$\mathsf{10x = 6}$

$\boxed{\boxed{\mathsf{x = \dfrac{3}{5}}}}$
