Answer:
2x (x - 4)
Step-by-step explanation:

solve for "k" to find "k", or the "constant of variation"
Use substitution when either and x or y is given, for instance: x = 2y + 3 or y = 8x - 9.
Use elimination when a number from both equations can cancel each other out, for example:
2x + 3y = 19
-2x + 7y = 12
Hope this helps!
