Metodo de reduccion4y + 2x = 98x - 4y = 4?

Metodo de reduccion 4y + 2x = 9 8x - 4y = 4.

En resumen

4y + 2x = 9 4y = 9 - 2y y = <img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B9-2x%7D%7B4%7D%20" /> 8x - 4(<img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B9-2y%7D%7B4%7D%20" />) = 4 8x - 36 + 8y = 4 8x + 8x = 4 + 36 16y = 40 x = 40 / 16 x = 5 / 2 4y + 2(<img src="https://tex.z-dn.

4y + 2x = 9

4y = 9 - 2y

y = <img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B9-2x%7D%7B4%7D%20" />

8x - 4(<img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B9-2y%7D%7B4%7D%20" />) = 4

8x - 36 + 8y = 4

8x + 8x = 4 + 36

16y = 40

x = 40 / 16

x = 5 / 2

4y + 2(<img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B5%7D%7B2%7D%20" />) = 9

4y + <img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B10%7D%7B2%7D%20" /> = 9 mcm = 2

8y + 10 = 18

8y = 18 - 10

8y = 8

y = <img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B8%7D%7B8%7D%20" />

y = 1.
