Ejercicio 1
\[5x + 5y = 20x \atop -2x + 2y = -28x\]
\[x = \boxed{\phantom{\rule{2em}{1.2em}}}, y = \boxed{\phantom{\rule{2em}{1.2em}}}\]
\[x = \boxed{\phantom{\rule{2em}{1.2em}}}, y = \boxed{\phantom{\rule{2em}{1.2em}}}\]
Ejercicio 2
\[-4x - 2y = 4x \atop x - y = 11x\]
\[x = \boxed{\phantom{\rule{2em}{1.2em}}}, y = \boxed{\phantom{\rule{2em}{1.2em}}}\]
\[x = \boxed{\phantom{\rule{2em}{1.2em}}}, y = \boxed{\phantom{\rule{2em}{1.2em}}}\]
Ejercicio 3
\[x - 2y = -4x \atop -3x - 4y = -28x\]
\[x = \boxed{\phantom{\rule{2em}{1.2em}}}, y = \boxed{\phantom{\rule{2em}{1.2em}}}\]
\[x = \boxed{\phantom{\rule{2em}{1.2em}}}, y = \boxed{\phantom{\rule{2em}{1.2em}}}\]
