Respuesta:
x = -4/21 y = 31/21
Explicación paso a paso:
Método de reducción:
5x+2y=2(x3)
−3x+3y=5(x5)
15x + 6y = 6
-15x + 15y = 25
21y = 31 => y = 31/21
5x + 2(31/21) = 2
5x = 42/21 - 62/21
5x = -20/21 => x = -4/21
Comprobación:
5(-4/21) + 2(31/21) = 2
-20/21 + 62/21 = 2
42/21 = 2 => 2 = 2
-3(-4/21) + 3(31/21) = 5
12/21 + 93/21 = 5
105/21 = 5 => 5 = 5
RPTA: x = -4/21 y = 31/21
