Resumen - Soluciones
Solución 1
\[4x - 4y = -12 \atop 5x + 5y = 85\]
\[x = \boxed{7}, y = \boxed{10}\]
\[x = \boxed{7}, y = \boxed{10}\]
Solución 2
\[x + y = -10 \atop 2x + 3y = -24\]
\[x = \boxed{-6}, y = \boxed{-4}\]
\[x = \boxed{-6}, y = \boxed{-4}\]
Solución 3
\[x^2 - 3y = 58 \atop 3x + 4y = -33\]
\[x = \boxed{-7}, y = \boxed{-3}\]
\[x = \boxed{-7}, y = \boxed{-3}\]
Solución 4
\[x^2 + 5y = -19 \atop 2x - 5y = 18\]
\[x = \boxed{-1}, y = \boxed{-4}\]
\[x = \boxed{-1}, y = \boxed{-4}\]
