Resposta:

$\textsf{Leia abaixo}$

Explicação passo-a-passo:

$\mathsf{x-2=8 }$

$\mathsf{ x=8+2}$

$\boxed{\boxed{\mathsf{ x=10}}}$

$\mathsf{ 3x-8=13}$

$\mathsf{3x=13+8 }$

$\mathsf{3x=21 }$

$\mathsf{x=\dfrac{21}{3} }$

$\boxed{\boxed{\mathsf{ x=7}}}$

$\mathsf{ 8x-9=2x+11}$

$\mathsf{8x-2x=11+9 }$

$\mathsf{ 6x=20}$

$\boxed{\boxed{\mathsf{x=\dfrac{ 10}{3}}}}$
