2x + 3y = 12
x - y = 1
DESPEJAMOS X :
x = 1 + y
REEMPLAZAMOS X:
2 (1 +y) + 3y = 12
2 + 2y + 3y = 12
5y = 12 - 2
5y = 10
y = 10 / 5
(y = 2)
CON EL VALOR DE Y, HALLAMOS EL VALOR DE X
2x + 3(2) = 12
2x + 6 = 12
2x = 12 - 6
2x = 6
x = 6 / 2
(x = 3)
COMPROBAMOS:
2 (3) + 3 (2) = 12
6 + 6 = 12
12 = 12
3 - 2 = 1
1 = 1
ESPERO HABERTE AYUDADO, BONITA NOCHE!
