Explicación paso a paso:

$\begin{bmatrix}5x+2y=1\\ -3x+3y=5\end{bmatrix}\\\\\\\mathrm{Sustituir\:}x=\frac{1-2y}{5}\\\\\\\begin{bmatrix}-3\cdot \frac{1-2y}{5}+3y=5\end{bmatrix}\\\\\\\begin{bmatrix}\frac{-3+21y}{5}=5\end{bmatrix}\\\\\\\mathrm{Para\:}x=\frac{1-2y}{5}\\\\\\\mathrm{Sustituir\:}y=\frac{4}{3}\\\\\\x=\frac{1-2\cdot \frac{4}{3}}{5}\\\\\\x=-\frac{1}{3}\\\\\\\mathrm{Las\:soluciones\:para\:el\:sistema\:de\:ecuaciones\:son:}\\\\\\x=-\frac{1}{3},\:y=\frac{4}{3}$
