Respuesta:
x = 5 y = 2
Explicación paso a paso:
Método de igualación:
3x+5y=25 => x = 25 - 5y/3
4x-4y=12 => x = 12 + 4y/4
25 - 5y/3 = 12 + 4y/4
100 - 20y = 36 + 12y
64 = 32y => y = 2 x = 5
Comprobación:
3(5) + 5(2) = 25 => 15 + 10 = 25 => 25 = 25
4(5) - 4(2) = 12 => 20 - 8 = 12 => 12 = 12
RPTA: x = 5 y = 2
