Answer:

Answer is B

Explanation:

$12x - y = 25 \\ 9x + y = 17 \\ x = (17 - y)/(9) \\ 12( (17 - y)/(9) ) - y = 25 \\$

$(204)/(9) - (12)/(9) y - y = 25 \\ (204)/(9) - (21y)/(9) = 25 \\ - (21y)/(9) = 25 - (204)/(9) \\ - (21y)/(9) = 2.33 \\ - 21y = 20.997 \\ y = - 0.99$

$y = - 1 \\ x = (17 - y)/(9) \\ x = (17 - - 1)/(9) = (18)/(9) \\ x = 2$
