X = 2y + 15 / 7x = 5y - 3 / - 6URGE?

X = 2y + 15 / 7 x = 5y - 3 / - 6 URGE.

En resumen

X = 2y + 15 / 77x = 14y + 157x - 14y = 15 (2) x = 5y - 3 / - 6⇒x = 5y + 1 / 22x = 10y + 12x - 10y = 1 ( - 7) 14x - 28y = 30 - 14x + 70y = - 7 42y = 23y = 23 / 422x - 10(23 / 42) = 12x = 1 - 230 / 42x = 94 / 21÷2x = 47 / 21.

X = 2y + 15 / 77x = 14y + 157x - 14y = 15 (2)

x = 5y - 3 / - 6⇒x = 5y + 1 / 22x = 10y + 12x - 10y = 1 ( - 7)

14x - 28y = 30 - 14x + 70y = - 7

42y = 23y = 23 / 422x - 10(23 / 42) = 12x = 1 - 230 / 42x = 94 / 21÷2x = 47 / 21.
