Explicação passo a passo:

$\begin{cases}\mathsf{\dfrac{x}{y} = \dfrac{3}{8}}\\\mathsf{y - x = 40}\end{cases}$

$\mathsf{\dfrac{y - 40}{y} = \dfrac{3}{8}}$

$\mathsf{8y - 320 = 3y}$

$\mathsf{5y = 320}$

$\mathsf{y = 64}$

$\mathsf{x = 64 - 40}$

$\mathsf{x = 24}$

$\boxed{\boxed{\mathsf{\dfrac{3}{8} = \dfrac{24}{64}}}}$
