Question

Use the elimination method to solve the system of equations. Choose the correct ordered pair
​

Answer 1

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`
