Resposta:

Explicação passo a passo:

$\begin{cases}\mathsf{-x + 2y = -3}\\\mathsf{5x - 2y = 1}\end{cases}$

$\mathsf{-x + 5x = -3 + 1}$

$\mathsf{4x = -2}$

$\boxed{\boxed{\mathsf{x = -\dfrac{1}{2}}}}$

$\mathsf{\dfrac{1}{2} + 2y = -3}$

$\mathsf{2y = -3 - \dfrac{1}{2}}$

$\mathsf{2y = -\dfrac{7}{2}}$

$\boxed{\boxed{\mathsf{y = -\dfrac{7}{4}}}}$
