Solve the system of equations by using elimination. Input your answer as an ordered pair.

`{(24 x-24 y,=,-168),(-12 x+12 y,=,84) :}`

If the system is dependent, enter the line on which the solutions are found in the form `y = mx + b`.

Box 1: Enter your answer as a point. Example: (2,5.5172)

Box 2: Enter your answer as an equation. Example: y=3x^2+1, 2+x+y=3
Be sure your variables match those in the question
