y = x + 3000

5x + 5y = 45000

5x + 7(x + 3000) = 45000

5x + 7x + 21000 = 45000

12x = 45000 - 21000

12x = 24000

x = 24000 / 12

(x = 2000)

REEMPLAZAMOS X PARA HALLAR Y

y = 2000 + 3000

(y = 5000)

COMPROBAMOS!

5000 = 2000 + 3000

5000 = 5000

5(2000) + 7(5000) = 45000

10000 + 35000 = 45000

45000 = 45000
